Answer:
Following are the solution to the given question:
Explanation:
The material is necessary to cook since frying is a speedy process for evaporation.
Drug A is now in the compressed fluid area, and the material would not boil if the pressure is chilled. Because the ship is solid, its substance A claim is false.
Unless the volume comprises of a drop in the heat, the B substance reaches a vapor pressure area and a wet region. That's the area that melting may occur. His claim for material B could therefore be true.

Answer:
7.72 seconds
The answer is not realistic as the time is very less to reach to a speed of 100 km/hr
also, we have not taken other factors into consideration like wind drag etc.
Explanation:
Data provided in the question:
Mass of the engine = 1500 kg
Power rating = 75 kW = 75,000 W
Initial speed, v₁ = 0
Final speed = 100 km/hr = = 27.78 m/s
Now,
Power = Work done ÷ Time
also,
Work done = Final energy - Initial energy
=
=
= 578703.70 J
thus,
75,000 = 578703.70 ÷ time
or
time = 7.716 s ≈ 7.72 seconds
The answer is not realistic as the time is very less to reach to a speed of 100 km/hr
also, we have not taken other factors into consideration like wind drag etc.

Explanation:
Answer:
a mass of water required is mw= 1273.26 gr = 1.27376 Kg
Explanation:
Assuming that the steam also gives out latent heat, the heat provided should be same for cooling the hot water than cooling the steam and condense it completely:
Q = mw * cw * ΔTw = ms * cs * ΔTw + ms * L
where m = mass , c= specific heat , ΔT=temperature change, L = latent heat of condensation
therefore
mw = ( ms * cs * ΔTw + ms * L )/ (cw * ΔTw )
replacing values
mw = [182g * 2.078 J/g°C*(118°C-100°C) + 118 g * 2260 J/g ] /[4.187 J/g°C * (90.7°C-39.4°C)] = 1273.26 gr = 1.27376 Kg
