Answer:
warmer air
Explanation:
the particles are more excited which increases the probability that the particles will bump into each other

Answer:
Apparent depth = 45 cm
Explanation:
The refractive index of water in a pool, n = 4/3
Real depth, d = 60 cm
We need to find its apparent depth when viewed vertically through air. The ratio of real depth to the apparent depth is equal to the refractive index of the material. Let the apparent depth is d'. So,

So, the apparent depth is 45 cm.
