It becomes brighter

Its brightness peaks at shorter wavelengths

It changes color

All of the above

Explanation / Answer

2

All of the above'

since L*T = constant = 0.0029

also I = AE sigma T^4

when body heats, its temperature increases, so it becomes brigther

the as LT is cosntant, L decrases, wavelgnth becomes shorter,

thus colour also changes
