The density of liquid mercury is 13.6 g/mL. What is its density in units of ? (2.54 cm = 1 in., 2.205 lb = 1 kg)

nalin [4]

Correct question

The density of liquid mercury is 13.6 g/mL. What is its density in units of lb/in3? (2.5 cm = 1 in., 2.205 lbs= 1 kg., 1000 g =1 kg, 1 mL = 1 cm³)

Answer:

$\rho0.4916\ lb/in^3$

Explanation:

Given that;-

The density = 13.6 g/mL

Also, 1 kg = 2.205 lb

1 kg = 1000 g

So, 1000 g = 2.205 lb

1 g = 0.002205 lb

Also,

1 in = 2.54 cm

1 in³ = 16.39 cm³

1 cm³ = 1 mL

So, 1 in³ = 16.39 mL

1 mL = 0.061 in³

The expression for the calculation of density is shown below as:-

$\rho=\frac{m}{V}$

Thus,

$\rho=\frac{13.6\ g}{1\ mL}=\frac{13.6\times 0.002205\ lb}{0.061\ in^3}=0.4916\ lb/in^3$

_____ is a measure of the average kinetic energy of a gas. Density Enthalpy Pressure Temperature

Fiesta28 [93]

Answer:

Temperature

Explanation:

Temperature is a measure of the average kinetic energy of the particles in a sample of a gas.
Kinetic energy is the energy possessed by an object because of its motion. As an object absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
When the temperature of a body or an object is increased and hence the heat, there is more movement or vibration of particles which translates to more kinetic energy.
