A night storage heater has a large block of material that is heated by electricity during the night. In the daytime, the block cools and gives out thermal energy to the room. Which thermal capacity and which night-time temperature rise will result in the greatest amount of energy being stored in the block?
- Athermal capacity of block: large; night-time temperature increase: large
- Bthermal capacity of block: large; night-time temperature increase: small
- Cthermal capacity of block: small; night-time temperature increase: large
- Dthermal capacity of block: small; night-time temperature increase: small
