Answer:
3-³ x (1/3)^-5 x (1/3)-²
Applying Indices
3^-3 x (3-¹)^-5 x (3-¹)^-2
When the negative signs interact
they become positive
We now have
3^-3 x 3^5 x 3^2
= 3^-3 x 3^7
=3⁴.

occurs in fluids
Explanation:
Convection is a mode of heat transfer that occurs in fluids.
There are three types of heat transfer:
conduction convection and radiation
- Conduction is a mode of heat transfer that involves an actual contact between the molecules of the medium. It occurs mostly in solids
- Radiation uses electromagnetic waves to transfer heat between two bodies or places. It does not require a material medium. The heat of the sun reaches us by radiation.
- Convection is a mode of heat transfer in fluids. It involves the density differences between hot and cold liquids and gases.
- Water boils by convection currents.
