Answer 1

4. A psychrometer is used to measure relative humidity.5. The amount of decrease in temperature from the dry bulb to the wet bulb is called the wet bulb depression.6. The term for the ratio of water vapor in the air to the amount of water needed to saturate the air is relative humidity.7. Relative humidity is expressed as a percentage.8. The temperature at which condensation occurs is called the dew point.9. The amount of water vapor in the air is also known as humidity.10. Warm air can hold more water vapor than cold air.11. A psychrometer works by using two thermometers, one with a dry bulb and one with a wet bulb. The wet bulb is covered with a cloth soaked in water. When the air is blown over the wet bulb, the water evaporates, causing the temperature of the wet bulb to decrease. The difference in temperature between the dry bulb and the wet bulb can be used to calculate the relative humidity.12. Albedo is the measure of the reflectivity of a surface. It is the ratio of the amount of light reflected by a surface to the amount of light incident on it.13. Temperature is a measure of the average kinetic energy of the molecules in a substance. It determines the direction of heat transfer, with heat moving from warmer objects to cooler ones.14. Heat in the atmosphere can be transferred through conduction, convection, and radiation.15. The Earth is not the same temperature everywhere because of factors such as latitude, altitude, proximity to bodies of water, and ocean currents. For example, areas closer to the equator receive more direct sunlight and are warmer, while areas at higher latitudes receive less direct sunlight and are cooler.
