Answer:
Heat required to melt 1 lb of ice is 151.469 KJ
Explanation:
We have given mass of ice = 1 lb
We know that 1 lb = 0.4535 kg
Latent heat of fusion for ice =334 KJ/kg
Amount if heat for fusion of ice is given by
, here m is mass of ice and L is latent heat of fusion
So heat 
So heat required to melt 1 lb of ice is equal to 151.469 KJ
As pressure increases, temperature must <span>increase</span> for water to remain in a gaseous state.
Answer:
The equation of motion is derived based on the Newton’s laws of motion. And it changes accordingly when an object changes with uniform velocity.
Given is that object moves with uniform velocity, that is no change in velocity so there will no acceleration.
As we know
Here, u = v (due to uniform velocity)
.
1st equation of motion is, v = u + at
2nd equation of motion,
3rd equation of motion,
.
