In warm regions where tropical plants grow but the temperature may drop below freezing a few times in the winter, the destruction of sensitive plants due to freezing can be reduced by watering them in the evening. Explain
When night falls, the temperature of the earth’s surface starts to drop. On a cool night, dew starts to form on the grass as water vapor condenses. Once dew starts to form, the rate of temperature decrease slows. Explain why this change occurs.
The temperature of the ocean off the coast of New Jersey ranges from about 3 °C in late winter to about 24 °C in late summer. If we assume that the ocean temperature is representative of a layer that is 25 m deep and the only exchange of energy is at the ocean surface, what is the average energy flux at ocean surface that would be required to account for this temperature change?

- One easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose the house already had 15 cm of fiberglass insulation in the attic and in all the exterior surfaces. If you added an extra 8.0 cm of fiberglass to the attic, then by what percentage would the heating cost of the house drop? Take the single story house to be of dimensions 10 m by 15 m by 3.0 m. Ignore air infiltration and heat loss through windows and doors.arrow_forwardFor the human body, what is the rate of heat transfer by conduction through the body’s tissue with the following conditions: the tissue thickness is 3.00 cm, the change in temperature is 2.00C, and the skin area is 1.50m2. How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)arrow_forwardGlobal warming will result in sea level rise. Assume that i) 2/3 or the earth's surface is oceans with average depth of the oceans is 3000m ii) that sea level rise will not result in the increase in the surface area of the oceans iii) that all of the oceans' water is at a the same temperature of 20°C and has (volume) coefficient of thermal expansion of ß = 2 x 10-4 K-¹. How much will the sea level rise for a 3°C rise in the average water temperature? (You should neglects the effects from the ice caps melting due to this temperature rises.)arrow_forward

- 20) At room temperature, a typical person loses energy to the surroundings at the rate of 62 W. If this energy loss has to be made up by an equivalent food intake, how many kilocalories (food calories) does this person need to consume every day just to make up this heat loss? (1 cal = 4.186 J) A) 1500 kcal B) 1600 kcal C) 1000 kcal D) 1100 kcal E) 1300 kcalarrow_forward35. when we are hot, our body automatically increases the rate of perspiration. This helps our body to cool down, mainly because: (a) The more liquid (water) we loose, the less mass remains in the body, and therefore total internal energy of the body decreases. (b) The sweat evaporates, and it takes the heat of evaporation from our body. (c) The relative humidity in the vicinity of our body increases, causing the skin to "feel" colder even though temperature has not decreased. (d) Sweat is hot, therefore as body losses it, we feel colder.arrow_forwardSnakes and other reptiles that live on land warm up in the sun.
