If the water in the bathtub has a higher temperature than the air in the bathroom, which will occur?
no heat exchange will take place.
heat will flow from the water into the air.
cold will flow from the air into the water.

Heat will flow from the water into the air.

Explanation:

Natural flow of heat is always from higher temperature region to lower temperature region.

So here we know that water is at higher temperature and air in the room is at lower temperature

So natural flow of heat will take place from water to room air.

This flow may be due to convection heat flow or radiation heat flow.

So here correct answer would be

Heat will flow from the water into the air.

what was the answer?

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
