On a hot summer day, 3.50 ✕ 106 J of heat transfer into a parked car takes place, increasing its temperature from 36.5°C to 44.4°C. What is the increase in entropy (in J/K) of the car due to this heat transfer alone?
On a winter day, a certain house loses 5.80 ✕ 108 J of heat to the outside (about 550,000 Btu). What is the total change in entropy (in J/K) due to this heat transfer alone, assuming an average indoor temperature of 23.5°C and an average outdoor temperature of 5.30°C?

Heat Transfer 1 Problem 1 During a cold winter day, wind at 55 km/h is blowing parallel to a 4-m-high and 10-m-long wall of a house. If the air outside is at 5°C and the surface temperature of the wall is 12°C, determine (a) friction coefficient at the center of the wall (b) heat transfer coefficient at the center of the wall (c) drag force on the wall (d) the rate of heat loss from on the wall Use Table...
Heat conduction occurs through any material, represented here by a rectangular bar, whether window glass or walrus blubber. The temperature of the material is T2 on the left and T1 on the right, where T2 is greater than T1. The rate of heat transfer by conduction is directly proportional to the surface area A, the temperature difference T2 - T1, and the substance's conductivity k. The rate of heat transfer is inversely proportional to the thickness d. Q kA (T2-T)...

Which of the following statements is true () Increasing the air speed increases convective heat transfer () the thickness of the air film (coefficient) increases with air speed a) ) the air film (coefficient) is like an insulating blanket over the surface () the air film (coefficient) offers resistance against heat transfer The Reynolds number...
Additional info: Meal = 1720 Kilocalories Mass of myself = 50 kg The Joule () is the SI unit of energy. (J = kg:m? S2 A calorie is another unit of energy. The definition of a calorie is the amount of heat (energy) necessary to raise the temperature of Ig of water by 1° Celsius. Ig of water occupies 1 milliliter (ml) = 1 cubic centimeter (cm) of volume. lkcal=4186J Energy comes in many forms and energy may be converted...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
