WILL MAKE BRAINLIEST 1. A balloon is dunked into a tank of cold water. How will this affect the size of the balloon?

A. it will shrink.

B. it will grow

2. When a sample of gas is cooled, the particles of gas .

A. slow down

B. speed up

A. A. it will shrink.

A. slow down .

Explanation:

Hello there!

In this case, according to the gas laws, it is possible to answer to this questions:

1. Here, it is required to study a volume-temperature relationship by means of the Charles' law which states that the volume decreases as temperature does; for that reason, when dunking  the balloon into the cold water, one can notice A. it will shrink.

2. Here, according to the kinetic molecular theory, which states that higher temperatures provide higher amounts of energy to the molecules to move faster as they gain thermal energy; it is possible to infer that when a sample of gas is cooled, the particles of A. slow down  as they lose thermal energy.

explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
