The given question is incomplete. The complete question is as follows.
A 10 kg iron ball is dropped onto a pavement from a height of 100 m. If half of the heat generated goes into warming the ball,find the temperature increase of the ball. (In Sl units, the specific heat capacity of iron is 450 J/kg.C degree).
Explanation:
In the given case, when the ball comes in contact with the pavement then its kinetic energy will be equal to potential energy of the ball before it was dropped. Half the K.E heats the ball.
As K.E = P.E = mgh
So, mgh = 
= 10,000 joules
And, half of this is 5,000 joules
As we know that
Q = 
5000 = 
= 1.11 degrees
Also, in the given situation
Since there is an m on both sides of the equation, we will divide both sides by m and the resulting equation will be as follows.
As, the result is independent of mass which is why the result is the same for any ball of any mass.
Answer:
ΔP = -3556.36 Pa
Explanation:
Atmospheric pressure, P = 101300 Pa
Latent heat of boiling water, 
Boiling point at atmospheric pressure, T = 373.15 K
ΔT = 1 K
The change in volume as the water boils to vapor will be
Since the volume of vapor (
) is far greater than the volume of liquid (
)
Using the ideal gas equation:
R = 8.314 J/mol-K
ΔV = 0.0306 m³
Molecular weight of water, MW = 0.018 kg/mol
Using the Clausius - Clapeyron equation:
ΔP = -3556.36 Pa
But the pressure change is said to lower the boiling point of water, only a negative pressure change will lower the boiling point.
ΔP = 3556.36 Pa
Germanium as it has 32 protons
The atmosphere of earth is made of five main layers.
1) Troposphere : This is the lowest part of the atmosphere. Most of the air that makes up the atmosphere is present in this layer.
2) Stratosphere : This layer is present above troposphere and extends up to 50 km. It contains ozone layer which prevents the harmful ultraviolet rays from the sun from entering the lower troposphere
3) Mesosphere : The layer above stratosphere is known as mesosphere.
4) Thermosphere : The region lies above mesosphere.
5) Exosphere : The is the outermost region of the atmosphere.
From the above discussion we can see that the layer that lies between exosphere and mesosphere is Thermosphere
