How much energy is needed to heat 1 kg of sand, which has a specific heat of 664 J/(kg K), from 30°C to 50°C?

Q = nC∆T

here Q = energy required

n = amount of substance

C = specific heat

then

Q = 1×664×(50-30) = 13280 j Answer

hi,

the capital city of australia is canberra.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
