Pasteurization is used to heat milk and remove any disease-causing organisms. it does not change the nutritional value or taste of the food. some foods can also be pasteurized; however, if meat is heated, the value and taste change. which was developed to allow for a similar effect without the loss of food integrity

Irradiation

Explanation:

Food irradiation is the process in which the food or the packed food is treated under the ionizing radiation. These radiation are gamma rays, electron beams and x-rays.

The main aim of using this process is to increase the shelf life of the food without destroying the quality of food. This process is same as like of the pasteurization.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
