Question

A sample of neon, Ne, occupies 1700. mL at STP. At constant pressure, what temperature is necessary to increase the volume to 2100. mL?

Answer 1

The temperature must be 337.42 K.

Step-by-step explanation:

At constant pressure and number of moles, using Charles's law

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

Given ,

At STP,

T₁ = 273.15 K

V₁ = 1700 mL

V₂ = 2100 mL

T₂ = ?

Using above equation as:

`(1700)/(273.15)=(2100)/(T_2)`

`T_2=(2100\cdot \:273.15)/(1700)\ K`

The temperature must be 337.42 K.
