Vedclass · Answer

(D) When a fluid is heated from the bottom,the molecules at the bottom gain kinetic energy and move further apart,which causes the fluid to expand.As the fluid expands,its volume increases while its mass remains constant,leading to a decrease in density.Because the heated fluid is less dense than the cooler,denser fluid above it,the buoyant force causes the warmer fluid to rise.This continuous cycle of rising warm fluid and sinking cool fluid creates convection currents.

When fluids are heated from the bottom,convection currents are produced because
