The air in a tire pump has a volume of 1.50 l at a temperature of 5 degrees celcius. if the temperature is increased to 30 degrees celcius and the pressure remains constant, what is the new volume

The new volume is 1.63 L

Explanation:

Step 1: Data given

A tire pump has a volume of 1.5 L, while the temperature is 5 °C

When the temperature changes to 30 °C, the volume will change as well.

The pressure remains constant.

Step 2: Charles' gas law

Since the pressure is constant we can use the following formula:

V1/T1  = V2/T2

with V1 = the initial volume = 1.5L

with T1 = the initial temperature = 5 °C = 273.15 + 5 = 278.15 Kelvin

with V2 = the final volume = TO BE DETERMINED

with T2 = the final temperature = 30 °C = 273.15 + 30 = 303.15 Kelvin

Step 3: Calculate the new volume

1.5L/ 278.15 Kelvin = V2/303.15 Kelvin

V2 = (1.50L * 303.15 Kelvin) / 278.15 Kelvin = 1.63 L

When the temperature increased from 5°C to 30°C, the volume will change to 1.63 L

answer carbon and three oxygen atoms;

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
