FAQ about Specific Heat Capacity Calculator
What is specific heat capacity?
Specific heat capacity is a measure of how much heat energy is required to raise the temperature of a substance by one degree Celsius (or one Kelvin). It is measured in joules per gram per degree Celsius (J/g/°C).
What is the formula for specific heat capacity?
The formula for specific heat capacity (c) is:
c = Q / (m * ΔT)
where:
- c is the specific heat capacity (J/g/°C)
- Q is the heat energy added (J)
- m is the mass of the substance (g)
- ΔT is the change in temperature (°C)
How do I calculate specific heat capacity?
To calculate specific heat capacity, you need to know the amount of heat energy added to the substance, the mass of the substance, and the change in temperature. You can then use the formula above to calculate the specific heat capacity.
What are some units of specific heat capacity?
The most common unit of specific heat capacity is joules per gram per degree Celsius (J/g/°C). Other units include calories per gram per degree Celsius (cal/g/°C) and kilojoules per kilogram per degree Celsius (kJ/kg/°C).
What is a good specific heat capacity?
A good specific heat capacity is one that is high. This means that it takes a lot of heat energy to raise the temperature of the substance. Substances with high specific heat capacities are often used as thermal insulators.
What are some examples of substances with high specific heat capacities?
Some substances with high specific heat capacities include:
- Water (4.19 J/g/°C)
