A bicycle tire has a volume of 1.0 l at 22°c. if the temperature of the tire is increased to 52°c, what is the resulting volume
tresset_1 [31]

The relationship between the volume, temperature, and pressure of the gas can be given by Charles law. The volume of the tire is 1.1 L.

<h3>What is Charle's law?</h3>

According to Charles's law, the volume is directly proportional to the temperature of the gas at a constant pressure.

Charle's law can be shown as,

\rm \dfrac{V_{1}}{T_{1}} = \rm \dfrac{V_{2}}{T_{2}}

Given,

Initial volume = 1.0 L

Initial temperature = 295 K

Final volume = ?

Final temperature = 325 K

Substituting values in the above equation the final volume can be calculated as:

\begin{aligned}\rm V_{2} &= \rm \dfrac{V_{1}T_{2}}{T_{1}}\\\\&= \dfrac{ 1 \times 325}{295}\\\\&= 1.1\;\rm L\end{aligned}

Therefore, the final resulting volume of the tire is 1.1 L.

A person's heartbeat is 71 beats per minute. If his/her heart beats 3.1e9 times in a lifetime, how long (in whole years) does th
Sidana [21]

First step: identify how many heart beats in a year.

To determine the heart beats in a year multiply the heart  beats in a minute with (60\times 24\times 365) years.  

Thus, heart beats in a year comes out to be = 71 \times (60\times 24\times 365) years

= 37317600 heart beats in a year

Heart beats 3.1\times 10^{9} in a life time.

Thus, number of years he lives is calculated by the division of  heart beats in a year and heart beats in a life time.

Number of years he lives = \frac{3.1\times 10^{9}}{37317600}

= 8.3\times 10^{-8}\times 10^{9}

= 8.3\times 10

= 83.0 years

Thus, number of years he lives is 83.0 years
