Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow.

What is the solution to the problem rounded to the correct number of significant figures? 8.01 × 4.1 = ? A. 32.8 B. 32.84 C. 32.

<u>Answer:</u> The correct option is Option D.

<u>Explanation:</u>

Significant figures are defined as the figures that represent the digits of a number which carry an important contribution to the numerical value, starting with the first non-zero digit. For Example: 105.268 has 6 significant figures because every digit carry its own contribution towards the numerical value.

Whenever there is multiplication, the answer will contain the same number of significant figures as there are in the least precise numerical value.

Significant figures in 8.01 are 3 and that in 4.1 are 2.

So, the answer of these two numerical value will contain 2 significant figures.

$8.01\times 4.1=32.841\approx 33$

Hence, the correct option is Option D.
