Example: It takes 2000 Joules of energy to heat a block up 5 degrees Celsius – what is the heat capacity of the block? Heat Capacity = E / T Heat Capacity = 2000 Joules / 5 C Heat Capacity = 400 Joules per degree Celsius (J/C)
Example: It takes 2000 Joules of energy to heat a block up 5 degrees Celsius – what is the heat capacity of the block? Heat Capacity = E / T Heat Capacity = 2000 Joules / 5 C Heat Capacity = 400 Joules per degree Celsius (J/C)
Heat Capacity = E / T Heat Capacity of the block = 60 Joules / (20C - 8C) 60 Joules / 12 C Heat Capacity of the Block = 5 J/C
If you measure heat energy in calories and temperature in Kelvin, your final answer would be 300 C/K.
Heat Capacity: 50J / 5C Heat Capacity = 10 J/C
The specific heat of a material is constant. That means that all pure water has the same specific heat– . 417 J/C.
Example: “I have 100 grams of ice. It takes 406 Joules to raise the temperature of ice 2 degree Celsius– what is the specific heat of ice?”’ Heat Capacity for 100g Ice = 406J / 2C Heat Capacity for 100g Ice = 203 J/C Heat Capacity for 1g Ice = 2. 03 J/C per gram If you are confused, think of it this way – it takes 2. 03 Joules to raise every single gram of ice one degree. So, if we have 100 grams of ice we need 100 times as many Joules to heat it all.
Example:" If the specific heat of aluminum is . 902 Joules per gram, how many Joules does it take to raise 5 grams of aluminum 2 degrees Celsius? Energy Needed = 5g x . 902J/C x 2C Energy Needed = 9. 2 J
Example:" If the specific heat of aluminum is . 902 Joules per gram, how many Joules does it take to raise 5 grams of aluminum 2 degrees Celsius? Energy Needed = 5g x . 902J/C x 2C Energy Needed = 9. 2 J
