You are watching: Which statement defines the heat capacity of a sample?
A 1.20-g sample of propane (C3H8) is shed in a bomb calorimeter. The temperature of the calorimeter rises from 20.0°C to 30.0°C. The calorimeter has a mass of 2.000 kg and also a details warmth of 2.95 J/(g • °C). If the molar mass of propane is 44.0 g/mol, what is the molar warm of burning of propane?
When finish combustion of a 0.260-mol sample of a compound occurs in a bomb calorimeter, the temperature of the calorimeter increases from 20.0°C to 52.0°C. The mass of the calorimeter is 1.50 kg, and its specific warm is 3.410 J/(gi°C). What amount of warmth would certainly be created by burning 1 mol of the compound?
A sample of octane (C8H18) that has actually a mass of 0.750 g is shed in a bomb calorimeter. As a result, the temperature of the calorimeter increases from 21.0°C to 41.0°C. The certain warm of the calorimeter is 1.50 J/(g • °C), and its mass is 1.00 kg. How a lot warm is released throughout the combustion of this sample?
A sample of an unrecognized substance has actually a mass of 0.465 kg. If 3,000.0 J of heat is required to heat the substance from 50.0°C to 100.0°C, what is the particular heat of the substance?
A copper rod that has a mass of 200.0 g has actually an initial temperature of 20.0°C and also is heated to 40.0°C. If 1,540 J of heat are needed to warm the rod, what is the specific warm of copper?
the amount of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a consistent pressure
Complete combustion of a 0.600-g sample of a compound in a bomb calorimeter releases 24.0 kJ of heat. The bomb calorimeter has a mass of 1.30 kg and also a specific warmth of 3.41 J/(gi°C). If the initial temperature of the calorimeter is 25.5°C, what is its last temperature?
The molar warm of fusion for water is 6.01 kJ/mol. How a lot power should be added to a 75.0-g block of ice at 0°C to adjust it to 75.0 g of liquid water at 0°C?
