Answer:
1. Evaporation
2. Condensation
3. Precipitation
4. Runoff
Explanation:
The water cycle shows how water moves on the earth as it passes through different phases.
Water on land is stored in oceans, rivers and other water bodies. This water coupled with those in plants and animals are turned into vapor through EVAPORATION. Evaporation facilitates the movement of water on the surface into the atmosphere.
In the atmosphere, the vapor condenses on dust particles found up there. The vapors forms a nuclei around the dust particles and water condenses at the saturated vapor pressure. This forms cloud.
As the water collects more and more, gravity forces the water to fall in form of PRECIPITATION. The precipitation can be in form of snow or rainfall.
When precipitation occurs, they move on the surface as SURFACE RUNOFFS. Some of the runoff goes back into oceans and rivers. Others infiltrates into the ground and collects in the ground water pool under the subsurface. Subsurface water can also get into into other water bodies when the water table coincides with the steam level.
The water in these bodies can then go into the cycle again. The sun is the source of energy for this process.
Answer:
mass of water, mw = 300g = 0.3kg
∆Tw = (80 - 20) °C
volume of air, va = 100m³
mass of air, ma = 100g = 0.1kg
∆Ta = ?
H = mc∆T
Hw = mwcw∆Tw
Hw = 0.3*4200*60
Hw = 75600J
Hw = 75.6 kJ
All the above heat energy got absorbed by air,
that is; Ha = 75600J
since it's given that the heat was absorbed by a specific amount of volume of air
then specific capacity of volume of air is
then,
ca = <u>Ha</u><u> </u> × <u>density</u><u> </u>
ma temp
then,
Ha = vaca∆Ta
where, ca = volumetric heat capacity of air = 0.012kJ/m³°C
75.6kJ = 100m³ × 0.012kJ/m³°C × ∆Ta
75.6 = 1.2/°C × ∆Ta
∆Ta = 63°C
63°C is the temperature change in air.
O=C=O, it’s a double bond between the carbons and oxygen
The planet would be Uranus.
