When warm water is poured into a bowl of cool water, what thermal energy transfer occurs? 

⚪ The warm area stays warm, and the cool area stays cool.

⚪ Energy from the warm area moves to the cool area.

⚪ Energy from the cool area moves to the warm area.

⚪ warm and cool areas would have lower temperatures.

____ is the thermal energy transfer that occurs from the motion of fluid in a liquid or gas.a. Radiation
c. Convection
b. Conduction
d. Condensation

What type of energy transfer occurs when the heat in the sand transfers to the person's feet?

120 grams of boiling water (temperature 100° C, heat capacity 4.2J/gram/K) are poured into an aluminum pan whose mass is 1100 gramsand initial temperature 22° C (the heat capacity of aluminum is 0.9J/gram/K).

(a) After a short time, what is the temperature of the water?
Tfinal = C

(b) What simplifying assumptions did you have to make?

-Energy transfer between the system (water plus pan) and thesurroundings was negligible during this time.
-The heat capacities for both water and aluminum hardly change withtemperature in this temperature range.
-The thermal energy of the aluminum doesn't change.
-The thermal energy of the water doesn't change.


(c) Next you place the pan on a hot electric stove. While the stoveis heating the pan, you use a beater to stir the water, doing 26432J of work, and the temperature of the water and pan increases to77.8° C. How much energy transfer due to a temperature differencewas there from the stove into the system consisting of the waterplus the pan?
Q = J
