Specific Heat

What would be the effect on the particles if more heat is supplied to the system?

• They would slow down
• They would stop moving
• They would speed up
• There would be no effect

A high specific heat means...

• It heats up quickly with energy added
• It requires more energy to change temperature

If I heat up 2 pans of water one has 100 mL in it and one has 1000mL. Which one heats up the fastest?

• 100 mL
• 1000 mL
• They both heat up at the same speed
• They cool down.

Copper, Stainless Steel, Carbon Steel, and Zinc were all heated using the same thermal energy.  What material would be the coolest after being heated?

• Copper
• Carbon Steel
• Zinc
• Stainless Steel

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
