Find the ratio of the volume divided by the
Nataly [62]

From the pair of values given, the ratio of the volume to the temperature for the first data pair is, 0.0026 cm³/K

<h3>What is a Ratio?</h3>

A ratio is a comparison between two quantities showing how much one quantity differs from another.

From the data given, the first data pair is as follows ;

  • Temperature = 276 K
  • Volume = 0.72 cm³

Ratio of volume to temperature = volume / temperature

Ratio = 0.72 / 276

Ratio = 0.002608 cm³/K

The significant figure's rule for division is the least number of significant figures used in the operation.

The least significant figure of the values given is 2.

Therefore, the ratio of the volume to the temperature for the first data pair is 0.0026 cm³/K

jeka57 [31]
Friction is helpful:
- We use it to brake for cars
- We use it to fly planes
-We wouldn't be able to turn a door knob without friction ( Our hand would just slide off it)

Friction harmful:
-Our cars would get much better gas mileage without tire and air friction
- There would be no skinned knees if friction didn't exist (Like when your skating or football)
- We could do some pretty cool dance moves without friction
- Our shoes would last longer without friction
