Answer:
The minimum heat required is 171626 joules.
Explanation:
By First Law of Thermodynamics, the amount of heat (
), in joules, is equal to the change in internal energy of water. The minimum heat required is the sensible heat necessary to heat up the water. That is:
(1)
Where:
- Density of water, in kilograms per cubic meter.
- Volume of water, in cubic meters.
- Specific heat of water, in joules per kilogram-degree Celsius.
- Change in temperature, in degrees Celsius.
If we know that 
, 
, 
and 
, then the minimum heat required is:
The minimum heat required is 171626 joules.
The si unit for temperature is Kelvin(k)
Answer:
Heat Capacity = E / T.
- Find the difference in temperature for changes of multiple degrees.
- Add the appropriate units to your answer to give it meaning.
- Know that this equation works for cooling objects as well.
- Know that specific heat refers to the energy needed to raise one gram by one degree.
