Question

If the starting volume of a hot air balloon is 55,500 m3and the initial temperature is 21 °C, what is the temperature inside the balloon is the final volume is 74,000 m3.

Answer 1

T₂ = 392 K

Step-by-step explanation:

Given that,

Initial volume of the hot air balloon, V₁ = 55500 m³

Initial temperature, T₁ = 21°C = 294 K

Final volume, V₂ = 74000 m³

We need to find the final temperature inside the balloon. The relation between the temperature and volume is given by charles law i.e.

`(V_1)/(T_1)=(V_2)/(T_2)`

Where

T₂ is the final temperature

So,

`(V_1)/(T_1)=(V_2)/(T_2)\\\\T_2=(T_1V_2)/(V_1)\\\\T_2=(294* 74000 )/(55500 )\\\\T_2=392\ K`

So, the new temperature is 392 K.
