- The temperatures of objects A and B are measured, and it is seen that the temperature of B is 72 K more than that of A. If the temperatures had been measured in degrees C, what would have been the difference in the temperatures of the two? (please give detail explanation)One gram of water and 1 gram of soil (“land”) are at a temperature of 20°C (68°F). If 5 calories of heat are added to each, what will be the temperature of the water and what will be the approximate temperature of the soil?An architect knows that a home receiving a lot of exposure from the sun will benefit from the heating effects of sunlight if there is a lot of glass in the home's design. By which method of heat transfer will sunlight heat the home?
- The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?If the temperature of an object goes from 900 K to 9000 K, By what factor is its energy emitted per second increased?
