Why is it important to know the specific heat capacity of a substance?
Explanation: Specific heat capacity is a measure of the amount of heat energy required to change the temperature of 1 kg of a material by 1 K. Hence it is important as it will give an indication of how much energy will be required to heat or cool an object of a given mass by a given amount.
Why high specific heat capacity of water is important?
A high specific heat of a substance means that a large amount of heat is required to raise the temperature of the substance. Water covers around 70% of the Earth’s surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature.
Which substance do you think will have the highest specific heat capacity?
Lead
What is the real life example of specific heat?
Water has the highest specific heat of any liquid. It requires 4.184 Joules to raise the temperature of one gram of water by one degree Celsius. This is the most energy required to raise a liquid by one degree. Water’s high specific heat is very useful to life.
Why is high specific heat capacity important to life?
The resistance to sudden temperature changes makes water an excellent habitat, allowing organisms to survive without experiencing wide temperature fluctuation. Furthermore, because many organisms are mainly composed of water, the property of high heat capacity allows highly regulated internal body temperatures.
What does it mean to have a high specific heat capacity?
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat capacity which we’ll refer to as simply “heat capacity”, meaning it takes more energy to increase the temperature of water compared to other substances.
Why is the high specific heat of water important to Earth quizlet?
The high specific heat of water helps to 1) moderate temperature in coastal areas, 2) stabilize ocean temperatures, creating a favorable environment for marine life, 3) because it covers most of the earth it keeps temperature fluctuations within the limits for life, 4) helps organisms (that are made primarily out of …
How is water’s high specific heat important?
What is the value for specific heat of water?
The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.
How do you calculate water equivalent?
Equivalent Water = Mass x Specific Heat It is also possible to describe the water equivalent of a given body as the mass of water whose heat capacity equals the heat capacity of a given body.
What is the dimensional formula of frequency?
| Frequency | |
|---|---|
| Other units | Baud (Bd) cycles per second (cps) revolutions per minute (rpm or r/min) solar neutrino unit (SNU) |
| In SI base units | s−1 |
| Derivations from other quantities | f = 1 ∕ T |
| Dimension | |
What is the dimensional formula of frequency and tension?
Therefore, frequency is dimensionally represented as [M0 L0 T1].
How do you find the class frequency?
The relative frequency of a class is found by dividing the frequency by the number of values in the data sample – this gives the proportion that fall into that class. The cumulative relative frequency is found by dividing the relative frequency by the number in the sample.
