A night storage heater contains a large block of material that is heated electrically at night. In the daytime, the block cools and releases thermal energy into the room. Which thermal capacity and which night-time temperature increase would result in the greatest amount of energy being stored in the block?
- Alarge thermal capacity, large temperature increase
- Blarge thermal capacity, small temperature increase
- Csmall thermal capacity, large temperature increase
- Dsmall thermal capacity, small temperature increase
