Three portions of the same liquid are mixed in a container that prevents the exchange of heat with the environment. Portion A has a mass m and a temperature of 95.0 °C, portion B also has a mass m but a temperature of 88.0 °C, and portion C has a mass mc and a temperature of 34.0 °C. What must be the mass of portion C so that the final temperature Tf of the three-portion mixture is T₁ = 50.0 °C? Express your answer in terms of m; for example, mc = 2.20 m. mc = Number i Units *m

To help prevent frost damage, 4.00 kg of water at 0 is sprayed onto a fruit tree. (a) How much heat transfer occurs as the water freezes? (b) How much would the temperature of the 200-kg tree decrease if this amount of heat transferred from the tree? Take the specific heat to be 3.35k J/kg. , and assume that no phase change occurs in the tree.
The convection heat transfer coefficient for a clothedperson standing in moving air is expressed as h = 14.8V 0.69for 0.15 < V < 1.5 m/s, where V is the air velocity. For aperson with a body surface area of 1.7 m2 and an averagesurface temperature of 29°C, determine the rate of heat lossfrom the person in windy air at 10°C by convection for airvelocities of (a) 0.5 m/s, (b) 1.0 m/s, and (c) 1.5 m/s.
A glass window in a house has an area of 0.67 m^2 and a thickness of 2.4 mm. The temperature inside the house is 21 C, and the outside temperature is 0 C. How much heat is lost through the window in 1 hour (3600 s) due to conduction? Use 1.0 W/(m x C) for the thermal conductivity of the glass. How much heat is lsot through the window in 1 hour (3600 s) due to raditaion? ( assume the temperature of the rntire glass is 21 C for this probelem). Which mode of heat transfer (condutciton vs. raditiaon) accounts for the greater amount of heat loss?
