You apply a flame to 2 L of water for a certain time and its temperature rises by 1°C. If youapply the same flame for the same time to 4L of water, what happens to its temperature? . Why?
The amount of heat is negative when: 2 points
O The body loses heat
The body gains heat
The body is in a state of equilibrium (neither
losing nor gaining heat)
The body temperature is equal to the
surroundings
The temperature of the outside environment
is more than the temperature of the body
O to leave
Assume that the amount of energy needed to raise the average temperature of the atmosphere by 0.4°C is 2 × 1021J. Estimate how much burned fuel would be needed to give rise to this increase, assuming this were the only cause of changes in the earth's temperature. Hint: Assume that coal has an energy density of 24 megajoules per kilogram.

- A resting adult of average size converts chemical energy in food into internal energy at the rate 120 W, called her basal metabolic rate. To stay at constant temperature, the body must put out energy at the same rate. Several processes exhaust energy from your body. Usually, the most important is thermal conduction into the air in contact with your exposed skin. If you are not wearing a hat, a convection current of warm air rises vertically from your head like a plume from a smokestack. Your body also loses energy by electromagnetic radiation, by your exhaling warm air, and by evaporation of perspiration. In this problem, consider still another pathway for energy loss: moisture in exhaled breath. Suppose you breathe out 22.0 breaths per minute, each with a volume of 0.600 L. Assume that you inhale dry air and exhale air at 37C containing water vapor with a vapor pressure of 3.20 kPa. The vapor came from evaporation of liquid water in your body. Model the water vapor as an ideal gas. Assume that its latent heat of evaporation at 37C is the same as its heat of vaporization at 100C. Calculate the rate at which you lose energy by exhaling humid air.arrow_forwardWhy is a person able to remove a piece of dry aluminum foil from a hot oven with bare fingers, whereas a burn results if there is moisture on the foil?arrow_forwardWhat is the distinction between gas and vapor?arrow_forward

As it travels 16.8 m to home plate, the ball slows down to 42.5 m/s because of air resistance. Find the change in temperature of the air through which it passes. To find the greatest possible temperature change, you may make the following assumptions. Air has a molar specific heat of CP = 72IR and an equivalent molar mass of 28.9 g/mol. The process is so rapid that the cover of the baseball acts as thermal insulation and the temperature of the ball itself does not change. A change in temperature happens initially only for the air in a cylinder 16.8 m in length and 3.70 cm in radius. This air is initially at 20.0C.arrow_forwardIf you place 0 ice into 0 water in an insulated container, what will the net result be?
