Measurement of Specific Heat Capacity

What are the three materials used in the experiment?

• Brass, Copper, and Aluminium

• Steel, Iron, and Zinc

• Gold, Silver, and Platinum

• Wood, Plastic, and Glass

Why is it important to have a few drops of water in the hole before inserting the thermometer?

• To prevent air gap between the metal and the thermometer

• To increase the accuracy of the temperature reading

• To cool down the metal block

• To prevent the thermometer from breaking

What is the equation for specific heat capacity?

• Energy = Mass x Specific Heat Capacity x Temperature Change

• Energy = Mass x Specific Heat Capacity

• Energy = Power x Time

• Energy = Voltage x Current

What is the unit of specific heat capacity?

• J/kg°C

• g/°C

• W/s

• V/A

Why does the block heat up slowly at the beginning of the experiment?

• Because the heater needs to heat up first

• Because the power supply is not working properly

• Because the block is insulated

• Because the thermometer is not accurate

What is the more accurate way of measuring power?

• Using a joulemeter

• Using a voltmeter and ammeter

• Using a thermometer

• Using a stopwatch

What is the purpose of insulating the block?

• To prevent energy loss to the surroundings

• To increase the specific heat capacity

• To decrease the temperature change

• To make the experiment more accurate

What is the specific heat capacity of aluminium in J/kg°C?

• 900

• 1050

• 1900

• 3400

What can be done to compare the specific heat capacities of different materials?

• Repeat the experiment with different materials

• Increase the power supply voltage

• Use a different type of thermometer

• Change the mass of the block

How many minutes were the temperature readings recorded for?

• 5 minutes

• 10 minutes

• 15 minutes

• 20 minutes
