Answer:
0.25 cm³.
Explanation:
We shall apply Boyle's law to find the solution . According to it
PV = constant where P is pressure and V is volume of the gas.
P₁ V₁ = P₂V₂
1 x .5 = 2 x V₂
V₂ = 0.25 cm³.
Answer:
Explanation:
Q = m c Δt
heat withdrawn to lower temperature by 40° C
Q = 1 X 1000 X 40 = 40,000 calories.
Q = mL
heat withdrawn to freeze water at 0°C to ice
= 1 x 80000 = 80,000 calories
total heat to be withdrawn = 120,000 calories. = 120,000 x 4.2 = 504 ,000 Joules.
Answer:
0
Explanation:
Since no distance is given, the force is not doing any work
No work is done by the man since we do not know the distance or displacement.
Work is only said to be done when the force applied on an object moves it through a particular distance.
Work done = Force x distance.
Since no distance is given in this problem, we can as well assume that the force applied is doing no work on the object.
