What wil be answer of 2 question answer it I will mark you as brainliest answer.
options are
28 , 283, 293 and 566 ml ​

Answer 1

283 ml

Explanation:

Given: T₁ = 10 + 273 = 283K, T₂ = 20 + 273 = 293K

             V₁ = 283 ml = 0.283 L , V₂ = ?

According to Charl's law at constant pressure

V₁T₁ = V₂T₂

V₂ = V₁T₁/ T₂

    = 0.283 × 283/293

    = 0.283 ≈ 283 ml

 

Answer 2

Answer:

Option (c) is correct. 293 ml.

Explanation:

To find : New volume of gas means V₂.

Given that,

A gas at 10°C occupies a volume of 283 ml.

• T₁ is 10°C.
• V₁ is 283 ml.

Then, it is heated to 20°C.

• T₂ is 20°C.

Here, Pressure is constant.

We know,

Charles' Law :

• $\pmb{\sf \dfrac{V_{1}}{T_{1}} = \dfrac{V_{2}}{T_{2}}}$ [It is relation between the volume and the absolute temperature at constant pressure]

Conversion :

Absolute temperature means temperature in Kelvin.

We know,

If temperature is in celsius then we have to add 273 K in that temperature.

T₁ = 10°C = 10 + 273 = 283 K

T₂ = 20°C = 20 + 273 = 293 K

Now, Put all values :

$\implies \sf \dfrac{283}{283} = \dfrac{V_{2}}{293}$

$\implies \sf \dfrac{\cancel{283}}{\cancel{283}} \times 293 = V_{2}$

$\implies \pmb{\sf V_{2} = 293}$

Therefore,

New volume is 293 ml.
