Specific Heat

A high specific heat means...

• It requires less energy to change temperature
• It requires more energy to change temperature
• It heats up very quickly

If I have 2 blocks of Aluminium (one of 1kg and one of 10 kg) and heat them up with 6,000 Joules of energy.
Which one will have the SMALLEST change in temperature?

• 1 kg
• 10 kg
• They both heat up  to the same temperature
• It depends on the temperature of the room
