Answer:

it is 52.7

Step-by-step explanation:

so when it is 30 the degree is 5°

when it is 60, the degree is 10°

when it is 90, the degree is 15° and so on...

Answer:

T₂ = 695.33 K

Step-by-step explanation:

Given data:

Initial volume = 150 mL

Initial temperature = 25°C (25+273 = 298 K)

Final temperature = ?

Final volume = 350 mL

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

T₂ = V₂T₁ /V₁

T₂ = 350 mL × 298 K / 150 mL

T₂ = 104300 mL.K / 150 mL

T₂ = 695.33 K
