If 35cm cube of gas is heated from 14 degree celsius to 55 degree celsius.what is the new volume?
(V1/T1) = (V2/T2)
Remember T must be in kelvin.

Please
To find the new volume of the gas after it is heated, we need to make use of Charles's Law, which states that the volume of a gas is directly proportional to its temperature in Kelvin (assuming pressure and amount of gas are constant).
First, we need to convert the temperature from Celsius to Kelvin. The conversion formula is K = °C + 273.15.
Initial temperature in Kelvin = 14°C + 273.15 = 287.15 K
Final temperature in Kelvin = 55°C + 273.15 = 328.15 K
Now, we can use the formula for Charles's Law:
(V1/T1) = (V2/T2)
Where:
V1 = Initial volume of the gas
T1 = Initial temperature in Kelvin
V2 = Final volume of the gas (we need to find this)
T2 = Final temperature in Kelvin
Plugging in the values we have, we get:
(35 cm³ / 287.15 K) = (V2 / 328.15 K)
To find V2, we can rearrange the equation:
V2 = (35 cm³ / 287.15 K) * 328.15 K
Now, we can calculate the new volume:
V2 = (35 / 287.15) * 328.15 cm³ ≈ 39.95 cm³
Therefore, the new volume of the gas after heating from 14°C to 55°C is approximately 39.95 cm³.
