If two objects are placed together and neither one undergoes any change, they have the same...

Question

a) conductance

b) heat

c) temperature

d) resistance

Answer 1

They have the same temperature.

If they did NOT have the same temperature, then when placed next together, the colder one would warm up, and the warmer one would cool down. But since there is no change, they must have the same temperature, and the answer is 'C'.

(Of course this does not account for room temperature, which would warm or cool the objects depending on the relative temperature difference.)
