A student uses an electric heater and a joulemeter to find the specific heat capacity of an aluminium block.
The student's value is higher than the true value.
What is the most likely reason for this?
Some energy from the heater was transferred to the surroundings
The mass of the block was recorded as larger than its true value
The joulemeter recorded less energy than the heater supplied
The thermometer read 1 ∘C1\ {}^\circ\text{C}1 ∘C too high for every reading
