Calculation of heat capacity of energy storage container

How is energy stored as sensible heat in different types of materials?

Energy stored as sensible heat in different types of materials. Thermal energy can be stored as sensible heat in a material by raising its temperature. The heat or energy storage can be calculated as Heat is stored in 2 m3 granite by heating it from 20 oC to 40 oC. The denisty of granite is 2400 kg/m3 and the specific heat of granite is 790 J/kgoC.

What is the difference between heat energy and specific heat capacity?

Heat energy (Q): The thermal energy added to or removed from a substance. Specific heat (c): Energy required per unit mass to raise temperature by 1 degree. Use this Heat Capacity Calculator to solve for heat energy, mass, or specific heat capacity in heating/cooling problems.

How do you calculate temperature?

1 Decide what you’re solving for: heat energy \ (Q\), specific heat \ (c\), or mass \ (m\). 2 Enter the known values for the other variables and pick the correct units next to each input. 3 For temperature change, enter \ (\Delta T\) (final minus initial). Use the same unit family as your data (°C/K or °F).

How do you calculate heat energy stored in granite?

The thermal heat energy stored in the granite can be calculated as q = (2 m3) (2400 kg/m3) (790 J/kgoC) ( (40 oC) - (20 oC)) = 75840 kJ qkWh= (75840 kJ) / (3600 s/h) =21 kWh The heat required to to heat 1 pound of water by 1 degree Fahrenheit when specific heat of water is 1.0 Btu/lboF can be calculated as q = (1 lb) (1.0 Btu/lboF) (1 oF) = 1 Btu
