How do you appreciate the role of specific heat in our day to day life?

Specific heat gives the amount of heat energy required for heating a substance of 1 unit mass by 1 °C. So more the specific heat, more the energy required for heating the substance. 1) Utensils used for making tea or coffee, or cooking vegetables or rice are made of materials of low specific heat.

What role does Specific Heat play in keeping a watermelon?

Higher the specific heat capacity of a body, the more heat is required to raise the temperature of a body. Watermelon contains almost 92% water since the specific heat of water is too high 4200 J/kg K therefore the specific heat capacity of watermelon is also high i.e, it has a high capacity to absorb heat.

Why specific heat is different for different substances?

Each substance will have a different mass, so when the amount of heat and the change in temperature are held constant, the only variable is the mass. Therefore, because mass is the only variable, so because substances have different masses, they will have different specific heats.

How do you find the specific heat of a solid experimentally?

Explain the procedure of finding specific heat of solid…

1. Measure the mass of the calorimeter along with stirrer.Mass of calorimeter ,m1=
2. Now fill one third of the volume of calorimeter with water.
3. take a few lead shots and place them in a hot water or steam heater .
4. transfer the hot lead shots quickly into the calori meter (with minimum loss of heat).

What are the materials required to determine the specific heat of solid?

Material Required: Calorimeter, Thermometer, Stirrer, water, steam heater, wooden box and solid whose ‘S’ to be found. Procedure: Measure the mass of calorimeter with stirrer. Knowing the specific heats of calorimeter and water, we can calculate the specific heat of the solid (lead shots).

How do you determine the specific heat of lead shots?

Answer:

1. Fill a 250-mL beaker 3/4 full with water and heat until it is boiling gently.
2. While the water is heating, use a weighing boat to measure ~40 g of lead shot.
3. Transfer the lead shot to a large, dry test tube.
4. While the lead shot is heating, measure 25 mL of distilled water in graduated cylinder.

How do you measure the temperature of a solid?

A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.

What object is used to measure an object’s temperature?

One of the most common devices for measuring temperature is the glass thermometer. This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid. Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid.

What are two units that can be used to measure heat?

Heat is commonly expressed in either of two units: the calorie, an older metric unit, and the British thermal unit (Btu), an English unit commonly used in the United States. Scientists express heat in terms of the joule, a unit used for all forms of energy.

What are the techniques used to track heat flow?

One technique we can use to measure the amount of heat involved in a chemical or physical process is known as calorimetry. Calorimetry is used to measure amounts of heat transferred to or from a substance. To do so, the heat is exchanged with a calibrated object (calorimeter).

What is the symbol of heat capacity?

symbol C

What is the symbol of heat in chemistry?

symbol ΔH

What is heat in short answer?

Heat is a form of energy of motion of molecules constituting the body. The unit of heat is the same as that of energy. The S.I. unit of heat is Joule.
