- It helps in regulating extremes in the environment.
- It can be used as a car radiators.
<u>Explanation:</u>
- The amount of heat needed to raise a certain amount of temperature to the water is known as the specific heat of the water. For one gram of water to increase 1 degree celsius, water needs to absorb 4.184 J of heat.
Some of the uses of high specific heat of water are as follows,
- The temperature of the water will remain the same from day to night in ponds or sea. During day time, the hot air from the sea or pond rises while the cool air from the sea moves to take its place. During the night, the hot air from the land moves to take its place, giving rise to a land breeze and thus maintaining the environment.
- Another example, When water is circulated throughout an engine, heat will get absorbed. This water is pumped to a radiator and then disposed to the surrounding air.
I think the first one is 40*40
The ideal gas law allows a scientist to calculate the number of moles that the other gas laws do not. The ideal gas law is given as
P V = n RT
rearranging the equation by dividing both side by "RT", we get
PV/(RT) = nRT/(RT)
n = PV/(RT)
inserting the values of pressure, volume and temperature, we get number of moles.
I’m not sure if its correct but I think it’s focal Ray point
For concave mirrors, some generalizations can be made to simplify ray construction. They are: An incident ray traveling parallel to the principal axis will reflect and pass through the focal point. An incident ray traveling through the focal point will reflect and travel parallel to the principal axis.
