Question

Heat sponataneously flows from a cooler object to a warmer object.(3 points)

True

False
Why does an aluminum block feel colder to the touch than a paperback book when you pick them up even though both objects are at the same temperature?(3 points)

the paperback book is a better conductor of heat so it transfers heat away from your skin faster

the aluminum block and the paperback book will feel the same.

the aluminum block is a better conductor of heat so it transfers heat away from your skin faster

Answer 1

1) False. Heat spontaneously flows from warmer objects to cooler ones (second law of thermodynamics).

2) The correct choice is: "the aluminum block is a better conductor of heat so it transfers heat away from your skin faster."
Aluminum has much higher thermal conductivity than the paperback, so it draws heat from your skin more quickly, making it feel colder even though both are at the same temperature.
