Which phase of matter is made up of particles that are packed relatively close together, with an indefinite shape but a definite
Bezzdna [24]

property of gas

gas molecules are very loosely bonded with each other so the force between the molecules is very weak

Due to this weak force the molecules of gas can attain any shape and any volume.

So gas moles have no finite shape and no finite volume

Property of Solids

Solids are tightly packed and having very strong bond between the molecules

If all molecules are tightly bonded then they have always a finite shape and finite volume so in this case we can not change the volume or shape of the solids as it is fixed.

Property of Liquids

Liquid molecules are moderately bonded together and since the force is more than the force between the gas molecules so liquids have finite volume but indefinite shape

liquid attains the shape of the container but its volume is fixed

So in above all examples Liquid is correct answer

Kevin decides to soup up his car by replacing the car's wheels with ones that have 1.4 times the diameter of the original wheels
True [87]

Answer:

No.

Explanation:

Given that Kevin decides to soup up his car by replacing the car's wheels with ones that have 1.4 times the diameter of the original wheels. Note that the speedometer in a car is calibrated based on the tire's diameter and on the distance the tire covers in each revolution. (a) Will the reading of the speedometer change ?

Considering the formula

V = wr

Where

V = linear speed

W = angular speed

r = radius of the wheel.

But W = 2πrf

Where the the 2 and pi are constant. The radius of the first wheel will be small but counter balance with the larger frequency.

While the radius of the second wheel may be large but it will be of a small frequency.

We can therefore conclude that the reading on the speedometer will not change. Because speedometer will read the linear speed V.
