<u>Answer:</u> The new volume is 133.25cm^3

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=125cm^3\\T_1=30^oC=(30+273)K=303K\\V_2=?cm^3\\T_2=50^oC=(50+273)K=323K

Putting values in above equation, we get:

\frac{125cm^3}{303K}=\frac{V_2}{323K}\\\\V_2=\frac{125\times 323}{303}=133.25cm^3

Hence, the new volume is 133.25cm^3

To solve this we use <span>Charles' law whitch states that V1/T1=V2/T2.
So if T1=30 C, V1=123 cm^3 and T2=50 C ->  V2=(V1*T2)/T1
T2=208.33 cm^3

Density of water 1000kgper m^3 What will be the volume of 3500<br>kg water​
skad [1K]

Answer:

<em>The volume of water is 3.5 cubic meter</em>

Explanation:

<u>Density </u>

The density of a substance or material is the mass per unit volume. The density varies with temperature and pressure.

The formula to calculate the density of a substance of mass (m) and volume (V) is:

\displaystyle \rho=\frac{m}{V}

We are given the density of water as \rho=1,000\ kg/m^3.It's required to find the volume of m=3,500 kg of water. Solving for V:

\displaystyle V=\frac{m}{\rho}

\displaystyle V=\frac{3,500}{1,000}

V=3.5\ m^3

The volume of water is 3.5 cubic meter
