Liquid rising in a thermometer as temperature increases and it is an example of

Answer;

-Thermal expansion

Explanation;

Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature.

It is a fractional change in size of a material in response to a change in temperature. This includes…

-changes in length compared to original length (Δℓ/ℓ0) called linear expansion

-changes in area compared to original area (ΔA/A0) called areal expansion or superficial expansion

-changes in volume compared to original volume (ΔV/V0) called volumetric expansion or cubical expansion.

For most materials, over small temperature ranges, these fractional changes are directly proportional to temperature change (ΔT) and have the same sign, they are also higher for liquids than solids.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
