What is kinetic theory

1 answer:

6 0

The kinetic theory of gases describes a gas as a large number of submicroscopic particles, all of which are in constant, rapid, random motion. The randomness arises from the particles' many collisions with each other and with the walls of the container.

Label each of the following measurements by the quantity each represents. For instance, a measurement of 10.6kg/m3 represents de

postnew [5]

The quantities represented by each of the measurements are

5.0g/mL - Density

37s - Time

47J - Energy or Work

39.56g - Mass

25.3 cm3 - Volume

325 m/s - Time

500m2 - Area

30.23 mL - Volume

2.7 mg - Mass

0.005L - Volume

To determine the quantity each of the measurements represents, we will observe the units.

5.0g/mL

This represents density. Density is the ratio of mass to volume, and mass is measured in grams (g) while volume is measured in milliliters (mL)

37s

This represents time because time is measured in seconds (s)

47J

This represents Energy or Work because they are measured in Joules (J)

39.56g

This represents mass because mass in measured in grams (g)

25.3 cm3

This represents volume because volume is measured in cubic meters (cm³)

325 m s

This represents time. Time can be measured in milliseconds (ms)

500m2

This represents area because area is measured in square meters (m²)

30.23 mL

This represents volume because volume is measured in milliliters (mL)

2.7 mg

This represents mass because mass could be measured in milligrams (mg)

0.005L

This represents volume because volume is measured in liters (L)

Hence, the quantities represented by each of the measurements are

5.0g/mL - Density

37s - Time

47J - Energy or Work

39.56g - Mass

25.3 cm3 - Volume

325 m s - Time

500m2 - Area

30.23 mL - Volume

2.7 mg - Mass

0.005L - Volume
