Density MCQ Questions - Mass Transfer

Explanation: The density more precisely, the volumetric mass density; also known as specific mass

Explanation: Density of a substance is its mass per unit volume.

Explanation: Osmium and iridium are the densest known elements at standard conditions for temperature and pressure.

Explanation: The reciprocal of the density of a substance is occasionally called its specific volume, a term sometimes used in thermodynamics.

Explanation: In Homogeneous materials, The density at all points of a homogeneous object equals its total mass divided by its total volume.

Explanation: Paper density is used in pulp or fabric industry in order to measure of the mass of the product per unit of area for a type of paperboard.

Explanation: Density of sand can vary depending on the grain size and moisture content and how tightly it is compacted.

Explanation: The density of water increases between its melting point at 0 °C and 4 °C; similar behavior is observed in silicon at low temperatures.

Explanation: Cotton is a soft, fluffy staple fiber that grows in a boll. The fiber is spun into yarn or thread. Density of cotton is 80 kg/m^3 while that of clay, coal and banana are 1460 kg/m^3, 1350 kg/m^3 and 980 kg/m^3.

Explanation: If the body is not homogeneous, then its density varies between different regions of the object.
