Specific Heat Capacity: Mass, Temp, Time Factors

In summary, specific heat capacity is the amount of heat energy required to raise the temperature of a substance by 1 degree Celsius per unit mass. The larger the mass of a substance, the more heat energy is required to raise its temperature. As the temperature of a substance increases, its specific heat capacity decreases. Time does not directly affect specific heat capacity, but the longer a substance is heated, the more its temperature will increase, requiring a higher specific heat capacity. Specific heat capacity is calculated by dividing the amount of heat energy transferred to a substance by the product of its mass and the change in temperature.

Is it possible to find specific heat capacity given mass, initial and final temperature, and time? The liquid in question has not been given

If you know the power input and the rate of heat loss to the surroundings

As mgb_phys stated you need to know the heat transfer in/out of the mass or the boundary worked performed on/by it. If the mass is compressible, you may also need to know the initial and final pressures as well.
 

FAQ: Specific Heat Capacity: Mass, Temp, Time Factors

1. What is specific heat capacity?

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance by 1 degree Celsius per unit mass.

2. How does mass affect specific heat capacity?

The larger the mass of a substance, the more heat energy is required to raise its temperature. This is because the particles in a larger mass require more energy to move and vibrate.

3. How does temperature affect specific heat capacity?

As the temperature of a substance increases, its specific heat capacity decreases. This means that less heat energy is required to raise the temperature of the substance by 1 degree Celsius.

4. What is the relationship between time and specific heat capacity?

Time does not directly affect specific heat capacity. However, the longer a substance is heated, the more its temperature will increase, requiring more heat energy and therefore a higher specific heat capacity.

5. How is specific heat capacity calculated?

Specific heat capacity is calculated by dividing the amount of heat energy transferred to a substance by the product of its mass and the change in temperature. The resulting unit is Joules per gram per degree Celsius (J/g°C).
