Does a ping pong ball sink or float?
The ping pong ball is buoyant, it floats, and it seeks the highest surface. When the water in the cup is not filled to the top, the ball clings to the sides of the cup where the water is the highest.
What is the estimated volume of the golf ball?
2.482 cubic inches
How many golf balls can fit in a hole?
2 golf balls
Why is a golf hole 4.25 inches?
Making more putts means having more fun to recreational golfers, this line of thinking goes. So expect to see experiments with hole size continue periodically. Meantime, remember: the golf hole size is 4.25 inches because that’s the size the R&A decided, in 1891, to standardize.
What would be the most accurate reading for the mass of the ball?
404.2g
Is mass or volume more precise?
Mass is generally measured by instruments called balances. The volume of liquid can either be measured directly or can be weighed. Knowing the mass of liquid and the density we can get the volume. This method of determining volume is easy to carry out and is more accurate due to the high accuracy possible in weighing.
Which density determination is the most accurate?
Graduated Cylinder The most accurate way to determine an object’s volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces.
What is the most accurate density of the substance in g mL?
The volumetric pipette was the most accurate because both its percent error on all the measured densities and average density were the smallest; therefore, its density was the closest to the actual number of 1.00 g/mL.
How do you introduce density?
Introduce one lab BEFORE you teach what density is, and allow students to discuss why some objects sink, why some float, and how mass and volume are related. Then AFTER you teach what density is and how to calculate it, introduce another lab where students can actually measure the density of objects.
Is density intensive or extensive?
The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (V). Considering that mass and volume are both extensive properties, explain why their ratio, density, is intensive.
Why density is not an intensive property?
Density is an intensive property because there is a narrow range of densities across the samples. No matter what the initial mass was, densities were essentially the same. Since intensive properties do not depend on the amount of material, the data indicate that density is an intensive property of matter.
Which are the intensive properties?
An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Other intensive properties include color, temperature, density, and solubility.
Is heat capacity an intensive or extensive property?
The heat capacity C of a substance is the amount of heat required to change its temperature by one degree, and has units of energy per degree. The heat capacity is therefore an extensive variable since a large quantity of matter will have a proportionally large heat capacity.
Is heat capacity at constant volume intensive?
“The total heat capacity, C (Heat required to raise the temperature of the system by 1°C) is an intensive path function. On the other hand, CV(Molar heat capacity at constant volume) and CP (Molar heat capacity at constant pressure) are intensive but state functions.”
Why is pressure an intensive property?
Pressure does not depend upon the amount of substance because it is defined as force per unit area. The definition itself eliminates the need of looking for how much of quantity is causing that much pressure. Pressure is an intensive property (independent of amount).
Which is not intensive property?
Volume is not an intensive property.
Which out of the following is an intensive property?
Intensive properties: Properties which are independent of the amount of substance (or substances) present in the system are called intensive properties, e.g. pressure, density, temperature, viscosity, surface tension, refractive index, emf, chemical potential, sp. heat etc, These are intensive properties.
Is heat an intensive property?
Yes, Heat is a property of matter. Extensive properties (like mass) are dependent upon the amount of a substance, while intensive properties (like density) are independent of quantity. Heat is an extensive property, and is proportional to the total energy of all atoms in an object.
Is entropy an intensive property?
By contrast, extensive properties such as the mass, volume and entropy of systems are additive for subsystems….Specific properties.
| Extensive property | Entropy |
|---|---|
| Symbol | S |
| SI units | J/K |
| Intensive (specific) property | Specific entropy |
| Intensive (molar) property | Molar entropy |
Is length an intensive property?
Length is an extensive property and the ratio of two extensive property is always an intensive property. An intensive property can be used(not always) as a unit for an extensive property.
Why entropy is intensive property?
An extensive property is dependent on size (or mass), and like you said, entropy = q/T, and q in itself is dependent on the mass, so therefore, it is extensive. Mass is an extensive property. An example of an intensive property would be density of water.
Which of the following is an example of intensive property?
Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Color, temperature, and solubility are examples of intensive properties.
Which of these is an example of investigating an intensive property?
weighing sand in a bag measuring the length of wire determining if a rock is magnetic recording the volume of water in a cylinder.
Which of the following is an intensive variables?
Temperature is independent of the quantity of matter, hence it is an intensive variable. So the correct option is (D).
Which of the following is intensive quantity?
Both temperature and refractive index are intensive properties.
