1.
Which equation gives the electrical energy supplied by a heater?
E = I t / V
E = V + I + t
E = V / I t
E = V I t
2.
A student measures a value of c that is too high. The most likely cause is
the thermometer was cold
the heater was too powerful
energy lost to the surroundings
the mass was too large
3.
A 2.0 kg block receives 18 000 J and warms by 10 °C. What is c?
90 J/(kg °C)
900 J/(kg °C)
360 J/(kg °C)
1800 J/(kg °C)
4.
Why is water or oil placed in the thermometer hole of the block?
To improve thermal contact
To increase the mass
To insulate the thermometer
To cool the block
5.
Why is a liquid stirred during the experiment?
To reduce the mass
To remove the insulation
To add energy
To keep all the liquid at the same temperature
6.
A graph of energy supplied (y-axis) against temperature rise (x-axis) is straight with gradient 450 J/°C for a 0.50 kg sample. What is c?
225 J/(kg °C)
450 J/(kg °C)
900 J/(kg °C)
1800 J/(kg °C)
