Question

As a liquid undergoes a phase change to a solid stale, it releases heat while remaining at a constant temperature. absorbs heat while remaining at a constant temperature. releases heat as the temperature decreases. absorbs heal as the temperature increases. The vaporization of water vapor actually warms the surroundings cools the surroundings sometimes warms and sometimes cools the surroundings depending on the relative humidity at the time neither warms nor cools the surroundings The condensation of water vapor actually warms the surroundings cools the surroundings sometimes warms and sometimes cools the surroundings depending on the relative humidity at the time neither warms nor cools the surroundings Compared to cooler air, warm air can hold more water vapor less water vapor the same amount of water vapor less water vapor, the amount depending on the humidity The metric unit of heat called a calorie is the specific heat of water the energy needed to increase the temperature of 1 gram of water by 1 degree celcius equivalent to a little over 4 joules of mechanical work All of the above are correct An automobile has how many different devices that can cause it to undergo acceleration. None one two three or more Which quality has the greatest influence on the amount of kinetic energy that a large truck has while moving down the highway. mass weight velocity size

Explanation / Answer

44. Liquid phase change to solid state - realises heat as the temperature decreases : if you will observe to the water phase change to a ice ( solid) temperature of water is decrease during the process of phase changing to solid and heat releases.

45. vaporation of water vapour - somethies warm and sometimes cools the surroundings depending upon the relative humidity at the time : When water evaporates from the surface of the Earth, it cools the surface. This keeps the surface from getting too hot. But because that water vapor is also the atmosphere's primary greenhouse gas, water vapor acts to keep the Earth's surface warmer than it would otherwise be.  

46. The condensation of water vapour Acctuly - - warms the surroundings : As condensation occurs and liquid water forms from the vapor, the water molecules become organized in a less random structure, which is less random than in vapor, and heat is released into the atmosphere as a result. And it warms that surrounding.

47. Compared to cooled air warm air can hold - - more water vapour : Relative humidity is the amount of water vapor in the air in comparison to what the air can hold. A relative humidity of 40 percent means that the air is only 40 percent saturated with moisture and can hold more water vapor.

In general, for each 20 F decrease in temperature, the relative humidity doubles. This means that as the temperature goes up, the relative humidity decreases; in other words, with the same amount of water vapor, cold air is more saturated than warm air.
