While baking cookies, you make some terrible assumptions. You erroneously assume that the heat to your cookies is transferred exclusively through the aluminium cookie sheet with a thermal conductivity of 205-) You also erroneously assume that the total amount of heat transferred is all that matters for a good cookie. But let's take this poor assumptions and go with them. The recipe tells you to spread the room temperature (20) cookies into 1.9 cm diameter disks and bake them for 32 minutes at 170°C. You are impatient and bake your 3.7 cm diameter cookies at 342"C Assume the cookies are 5 mm thick both in the recipe and in your impatient adaptation. After how many seconds should you take your cookies out of the oven?

In this problem you will consider the balance of thermal energy radiated and absorbed by a person. Assume that the person is wearing only a skimpy bathing suit of negligible area. As a rough approximation, the area of a human body may be considered to be that of the sides of a cylinder length L = 2.0 m and circumference C = 0.8 m. For the Stefan-Boltzmann constant use o = 5.67 x 10-8 W/m2 /K4.

A granite ball of radius 4.00 m and emissivity 0.042 is heated to 150°C. (a) Convert the given temperature to Kelvin. (Enter your answer to at least the nearest Kelvin.) K(b) What is the surface area of the ball? m2(c) If the ambient temperature is 25.0°C, what net power does the ball radiate? W
To keep warm outdoors, your run a 1118W generator for 4 minutes to make yourself a 300mL cup of tea. If the water only warmed up 60.02°C during this time, how efficient is the process?
An enclosure is initially at the same temperature as the outside, which is 20°C. In it there are two 50 W lamps each, a 100 W TV, a 200 W refrigerator, which works 2/3 of the time, and a 500 W iron. Assuming that no heat is transferred through the walls, calculate the rate of increase of the energy content in the room, when all these appliances are turned on?
(1) What will be the effect on the particles if more heat flow out of the system? (a) They will stop moving (b) They will slow down (c) They will speed up (d) There will be no effect

An object with mass of 100 kg, moving at a speed of 20 m/s, collides with wall and is crushed. Calculate the heat released if it is 30% of the whole impact energy. /Give the answer in [J] /
For a refrigerator let us consider the following quantities: The absolute value of the amount of heat that a refrigerator absorbs from the cold reservoir (its internal part): |Q₁| The absolute value of the amount of heat that the refrigerator releases to the environment: |Q₂1. We can state that: a) 1Q₁1=1Q₂1 b) 1Q₁1>1Q₂1 c) IQ₂|>1Q11 d) whether | Q₁ | is greater than, less than or equal to Q₂ | depends on the performance of the cooler.
