What is the mass of 37 ml but has the density of 0.79 g/ml

From the information given, it is not clearly stated that the substance is a liquid but because the measurement has been indicated that it is 37ml. then we will assume this is a liquid. The density of the liquid is 0.79g/ml.

mass = density × volume

mass = 0.79g/ml × 37ml

mass = 0.79 × 37

mass = 29.23

Therefore the mass is 29.23 grams.

Mass is directly proportional to volume and density. If either density or volume  increases then mass increases also.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
