What is Guillaume puts a bottle of soft drink in a refrigerator and leaves it there until its temperature has dropped 18.6 K.

What is the magnitude of its temperature change |ΔT|= 18.6 K in degrees Celsius?

a pan of water is heated from 27 degrees celsius to 77 degrees celsius. what is the change in temperature on the Kelvin scale? answer in units of K.

A slab of glass has an area A(5m^2), thickness L(.005m) and thermal conductivity k=1 Watts/(m*K). One of its surfaces (Q) is maintained at temperature T1=23 degreec Celsius and the other surface (P) is maintained at a lower temperature T2= 45 degrees celsius. The rate of heat flow from Q to P is:

Two 50 g of ice cubes are dropped into 200g of water in a thermally insulated container. If the water is initially at 25 degrees Celsius, and the ice comes directly from a freezer at -15 degrees Celsius, what is the final temperature at thermal equilibrium? (a) What is the final temperature if only ice cube is used?
