Acertain quantity of a gas occupies 61.3 mlat 68◦c. if the pressure remains constant,what would the volume of the gas be at 17◦c? 1. 52 ml2. 72 ml3. 32 ml4. 92 ml

52 mL

Explanation:

Since the pressure of the gas remains constant, we can use the following gas law:

where:

is the initial volume

is the final volume

is the initial temperature

is the final temperature

Substituting numbers and re-arranging the equation, we find the final volume of the gas:

So the correct answer is

1. 52 mL

1m/s

Explanation: As the stationary ball is hit by the moving ball ,the two moves together after collision, with a single velocity. The attached photo further explains how the answer is calculated
