Which describes the amount of heat energy that is needed to raise the temperature of 1 kilogram of a substance by 1°C?
A
convection heat capacity
B
potential heat capacity
C
radiation heat capacity
D
specific heat capacity
D
specific heat capacity
D) specific heat capacity
The correct answer is D) specific heat capacity.
To determine the amount of heat energy required to raise the temperature of a substance, you need to know the specific heat capacity of that substance. Specific heat capacity (also known as specific heat) is a measure of how much heat energy is needed to raise the temperature of a given mass of a substance by a certain amount.
The formula to calculate the heat energy (Q) is:
Q = m * c * ΔT
Where:
- Q is the heat energy (in joules)
- m is the mass of the substance (in kilograms)
- c is the specific heat capacity of the substance (in joules per kilogram per degree Celsius)
- ΔT is the change in temperature of the substance (in degrees Celsius)
In this case, we're looking for the amount of heat energy needed to raise the temperature of 1 kilogram of a substance by 1°C. To do this, we need to use the specific heat capacity (c).
Therefore, the correct answer is D) specific heat capacity.
