Answer: Yes both gases would have the same entropy.
Explanation:
The formula for the change in the entropy is as follows,
Here, \Delta S is the change in the entropy, Q is the heat transfer and T is the temperature.
If the temperature of the system increases then there will be increase in the entropy as the randomness of the system increases.
In the given problem, if the both gases were initially at the same absolute temperature. Then there will be same entropy change in both gases.
Therefore, yes both gases would have the same entropy.
Solution :
Given data :
Mass of ice, m = 200 g
Mass of water, M = 500 g
Temperature of ice = 0°C
Temperature of water = 20°C
We known ;
The latent heat of fusion of water is
The specific heat of water, C = 4.18 kJ/kg K
a). Heat required to change the ice into water is :
J
Heat required to cool the warm water is :
From above result,
This means that total ice could not melt.
So, the temperature must be T = 0°C
b). Q' = mL
m = 0.1253 kg
m = 125.3 g
m = 125 g
Therefore, 125 g of ice had melted.
Swimming, because during swimming we use more muscles than when we sprint, stretch, etc..
Answer : The mass of the tennis ball is, 58.8 g
Solution : Given,
Momentum of tennis ball =
Velocity of tennis ball =
Momentum : It is equal to the product of the mass of object and the velocity of the object.
Formula used :
where,
p = momentum of an object
m = mass of an object
v = velocity of an object
Now put all the given values in the formula, we get the mass of an object.
(1 Kg = 1000 g)
Therefore, the mass of the tennis ball is, 58.8 g
