3) A hot pie is just taken out from an oven with a set temperature of 175°F. It is placed near a window with an ambient temperature of 68°F. After 3 minutes, the temperature of the pie is 150°F, determine how long it will take the pie have a temperature of 100°F. Determine also the time when the temperature of the pie is half a degree above the ambient temperature.

The tip of a soldering iron consists of a 0.6-cm- diameter copper rod, 7.6 cm long. If the tip must be 204C, what are the required minimum temperature of the base and the heat flow, in watts, into the base? Assume that h=22.7W/m2KandTair=21C.
Carrie is trying to figure out the number of calories in a cube of cheese. To do this, she pours 199.7 mL of water into an aluminum can suspended from a ring stand. She takes the temperature of the water, and finds it to be 19.8 degrees Celsius. Then, she places the 5.23 gram cube of cheese under the can and lights it on fire! While the cheese is burning and for a few minutes after it is done, Carrie records the temperature of the water, finding that it levels out at 47.9 degrees Celsius. How many calories of heat were gained by the water? Please answer to the nearest 0.1 calorie.
A tank of air is expanded via heat transfer at a constant pressure such that its volume is 2.5 times its original volume. If the initial temperature of the tank was 23 Celsius, what is the amount of heat transfer required for this process in kJ/kg? Calculate this with the following 3 approaches: Constant Specific Heats (use the average temp) The equation as seen on table A-2 Air property tables
There is a calorimeter composed of a thermally insulated container. Inside it are 1.2 kg of ice at −15 ∘C. How much mass of water at 60 ∘C needs to be added in the calorimeter for the final temperature to be 5 ∘C? If water vapor were introduced at 100 ∘C instead of water, how much mass of steam would have to be added for the final temperature to be 30 ∘C? What volume would the water vapor in the previous part occupy (before adding it to the calorimeter) if the pressure at which it is contained is 1.20 × 105 Pa? NOTE: The molar mass of water is 18 g / mol. ice = 2090 J / kg ∘C. water = 4180 J / kg ∘C. Lf, water = 3.33 × 105 J / kg. Lv, water = 2.26 × 106 J / kg
During the midday 2pm, the temperature of the water that is left out on a table is 18° If the temperature of the surrounding is 38°C and the water’s temperature heated up to 26°C at 2:25pm. After how many minutes will the water’s temperature be 32°C?
When a cake is removed from an oven, its temperature is measured at 3200F. Three minutes later its temperature is 21 OOF, How long will it take for the cake to cool off to a room temperature of 800F?
In a kitchen there are two identical pots that have been previously heated, one of the pans is filled with 500ml of Water at 100◦C and the other with 500 no of oil at 130◦C. After that, there is more fire that continues to introduce heat to both liquids. In that instant, a person who had cut 300 g of potato into small cubes at a temperature of 25◦C, decides to pour half the amount of potato in boiling water and the other half in burning oil. Knowing that Water density is the 1.00 g / ml; the oil density = 0.87 g / ml; theSpecific heat of water = 4186 J/ kg ·◦C, is theOil specific heat = 2000 J/ kg ·◦C is thePotato specific heat = 5530 J /kg ·◦C (a) Determine the temperature of the thermal equilibrium between the potatoes in water, and the same portion in oil, considering each cases as isolated systems.
3.) When a gas surrounded by air is compressed or expands adiabatically, its temperature rises or decreased even though there is no heat input or dissipated to the gas. Where does the energy come from to raise or lower the temperature?
An iron block cools down from 200°C to the room temperature of 27°C,when outdoor is 5°C, heating the room. Determine the maximum theoreticalamount of heat that can be supplied to the house as the iron cools down to27°C.
Calorimetry In a kitchen there are two identical pans that have been previously heated, one of the pans is filled with 1/2 liter of Water at 100◦C and the other with 1/2 liter of oil at 130◦C. After that, no there is more fire that keeps introducing heat to both liquids. In that instant, a person who had cut 300 grams of potato into small cubes at a temperature of 25◦C, decides to pour half the amount of potato in the boiling water and the other half in the burning oil. a) Determine the temperature of the thermal equilibrium between the pore potatoes in the water, and the same for nocao in the oil, considering each cases as isolated systems. (b) Explain why the thermal equilibrium temperatures in both cases are almost the same, mention the physical fundamentals that characterize that result. information in the image respectively: water density: oil density: specific heat of water: specific oil heat: specific heat of the potato:
(i) A can of soft drink at room temperature is put into the refrigerator so that it will cool. Would you model the can of soft drink as a closed system or as an open system? (ii) A candle is burning in a well-insulated room. Taking the room (the air plus the candle) as the system, determine if there is any heat transfer during the burning process. Explain how?
