When a sample of aluminium of unknown mass was subjected to 1.8 kJ of heat, the temperature of the aluminium sample increased from 26°C to 31°C. What was the mass of the sample? (specific heat of Al = 0.90 J/g°C)

Immediately, upon bringing a hot piece of metal into a room, the heat is felt from 5 m away. The type of heat transfer is probably
