vodka [1.7K]

Answer:

The average kinetic energy of a particle is proportional to the temperature in Kelvin.

Explanation:

The kinetic molecular theory states that particles of matter are in constant motion and collide frequently with each other as well as with the walls of the container.

The collisions between particles are completely elastic. The kinetic energy of the particles of a body depends on the temperature of the body since temperature is defined as a measure of the average kinetic energy of the particles of a body.

Therefore, the average kinetic energy of a particle is proportional to the temperature in Kelvin.

Answer:

0.895 g/mL

Explanation:

Step 1: Given data

Mass of liquid Z (m): 2.763 lb

Volume of liquid Z (V): 5.93 cups

Step 2: Convert "m" to grams

We will use the relationship 1 lb = 453.59 g.

2.763 lb \times \frac{453.59 g}{1lb} = 1,253g

Step 3: Convert "V" to milliliters

We will use the relationship 1 cup = 236.59 mL.

5.93cup \times \frac{236.59mL}{1cup} = 1.40 \times 10^{3} mL

Step 4: Calculate the density of the liquid Z

The density (ρ) of the liquid Z is equal to its mass divided by its volume.

\rho = \frac{m}{V} = \frac{1,253g}{1.40 \times 10^{3}mL  } = 0.895 g/mL
