Teaching UP B.Ed (Paper 1 & 2) Mock Test 2025 Physics Thermal Properties of Matter Newton’s law of cooling
A solid at a temperature (T) is kept in an evacuated chamber at temperature T0. (T0 < T). The rate at which the solid cools is proportional to
1
( T - T0 )
2
( T - T0 )2
3
( T - T0 )4
4
( T4 - T04 )
