What is one safety risk when using a beaker, electric heater, joulemeter, mass balance, and thermometer to determine the specific heat capacity of water?

What the question is asking

You are doing an experiment where electrical energy heats water in a beaker. The equipment list tells you there will be hot components and electricity, so you need to name one realistic hazard.

A clear, correct risk to state

• Burn/scald risk: the water and beaker become very hot, and the heater element can also be hot, so touching or spilling them can cause burns.

Other acceptable examples (any one would earn the mark)

• Electric shock if the heater or leads are damaged or used with wet hands.
• Cuts if the beaker breaks (glass hazard).

How to phrase it for full credit

Keep it short and specific, for example: "Hot water or the heater can cause burns."
