What fraction of the gas phase molecules initially present for 1.0 atm in the chamber are present at 1.0×10−10 torr?

vivado [14]

The fraction of gas phase molecules is calculated by the division of final pressure to the initial pressure.

Fraction = $\frac{P_{final}}{P_{initial}}$ (1)

Here, initial pressure = 1.0 atm

final pressure = $1.0\times 10^{-10} torr$

First, convert torr into atm

1 atm = 760 torr

final pressure = $\frac{1.0\times 10^{-10}}{760}$

= $1.316\times 10^{-13}atm$

Now, put the value of initial and final pressure in formula (1)

Fraction = $\frac{1.316\times 10^{-13}atm}{1.0 atm}$

= $1.316\times 10^{-13}$

Thus, fraction of the gas phase molecules = $1.316\times 10^{-13}$ $\simeq 1.3\times 10^{-13}$

When the alcohol thermometer is placed in 20∘c water, what temperature will the thermometer record?

Svet_ta [14]

The thermometer operates under the concept of the Zeroth Law of Thermodynamics. The thermometer displays the temperature of its surroundings, regardless of the identity of the substance. So, if the water is 20°C, then the thermometer displays 20°C.
