A student decided to measure the specific heat capacity for water. He took a heavy glass 250 cm3 beaker and filled it up to the 100 cm3 mark. He placed it on a retort stand and clamped the heating coil and thermometer above it so that they both dipped into the water. He connected the heating coil to the joulemeter and powerpack and switched on. He took the temperature and then waited until the thermometer reading had gone up by 10oC. He then switched off the powerpack and read the joulemeter. It read 5382 Joules. He then calculated the specific heat capacity of water as 5.382 J.

Discuss the errors in the student’s practical.

Just want to see if there are any that I missed.

Oh, I think the temperature would continue rising after he switched off the power pack. It should be read the highest rise in temperature, so dT must be greater -> heat capacity of water is lower (4.18 JkgK-1)

a few that immediately come to mind ....

specific heat capacity is not measured in J
lot of error in the measurement of 100cm3
heat losses
