- Object A is placed in thermal contact with a very large object B of unknown temperature. Objects A and B are allowed to reach thermal equilibrium; object Bs temperature does not change due to its comparative size. Object A is removed from thermal contact with B and placed in thermal contact with another object C at a temperature of 40C. Objects A and C are of comparable size. The temperature of C is observed to be unchanged. What is the temperature of object B?arrow_forwardWhy is a person able to remove a piece of dry aluminum foil from a hot oven with bare fingers, whereas a burn results if there is moisture on the foil?arrow_forwardSuppose you have 2.5kg of steam at 100 degrees celcius occupying 6.5 meters cubed at a pressure of 1.013 x 10^5 Pa. When the steam condenses to water at 100 degrees celcius it occupies a volume of 0.55 meters cubed.
