What is the boiling point of water when the atmospheric pressure exerted on the water is 81 kPa ?
stellarik [79]

Answer: The boiling point of water at 81 kPa will be 298.17 K.

Explanation:

The boiling point of water is 373 K at atmospheric pressure. So, to calculate the boiling point at 81 kPa, we use the law given by Gay-Lussac.

Gay-Lussac Law states that pressure is directly proportional to the temperature when volume and moles remain constant.

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2

where,

P_1\text{ and }T_1 = Initial pressure and temperature

P_2\text{ and }T_2 = Final pressure and temperature

We are given:

P_1=1atm=101.325kPa\\T_1=373K\\P_2=81kPa\\T_2=?K

Putting values in above equation, we get:

\frac{101.325kPa}{373K}=\frac{81kPa}{T_2}\\\\T_2=298.17K

Hence, the boiling point of water at 81 kPa will be 298.17 K.

What is the volume in mL of a cube with each side 80mm long ?
dem82 [27]
<h3>Answer:</h3>

512 mL

<h3>Explanation:</h3>

We are given;

  • A cube with a side 80 mm long or 8 cm long  

We are required to calculate the volume;

  • Volume refers to the amount of space an object occupies.
  • To calculate the volume of a cube we get the cube of its side;
  • That is, volume of the cube = l³

Therefore;

Volume = (8 cm)³

            = 512 cm³

But; 1 cm³ = 1 mL

Therefore, the volume of the cube in mL is 512 mL
