Answer:
Explanation:
Given
Temperature of gas at First stage 
Pressure of gas at First stage 
Volume Occupies 
If the Pressure and Temperature at second stage is


Using ideal gas Equation

where P=Pressure
V=volume
R=Universal Gas constant
T=Temperature
n=no of moles
as n and R is constant therefore

thus 


Answer:
C. Sunlight to electricity
Explanation:
Photo voltaic cells covert sunlight to the electricity. It absorbs the light from the sun and use that sunlight to create electric current. The number of photo voltaic cells are connected together in a solar panel to generate enough electricity to power up a home.

Explanation:
Answer:
B). 3.4 s
Explanation:
As we can see the graph is given between velocity and time
so here we can see that the velocity is changing here with time and initially for some time it moves with constant speed
Then it's speed decreases to next few second and then speed increases to its maximum value
The time after which velocity comes to its maximum value will reach after t = 3 s
so out of the all given options most correct option will be
