Answer:

1 g of water from 14 °C to 15 °C.

Explanation:

Heat may be defined as the form of energy. The heat can be absorbed during the reaction or heat can be released during the reaction depending upon the time of reaction.

The kilocalorie of heat is used to measure the heating or the metabolization of the food. The kilocalorie of heat means the amount of the heat that are required to raise the 1 gram or kilogram of water by 1 degree celcius. The 1 g of water has been raised by the difference of 1 1 degree celcius in14 °C to 15 °C.

Thus, the correct answer is option (A).

Answer:

Option-A

Explanation:

The unit of energy or work is done can be represented in the form of a calorie and since work done result in the increase of temperature therefore calorie can be expressed in terms of heat and temperature.

A calorie in terms of heat can be referred to as the amount of heat required to increase the temperature of 1 g of water upto 1°C that is from 14.5 °C to 15.5 °C.(standard temperature range for calculating calorie).

Similarly, a 1000 cal or 1 kcal can refer to as the amount of heat energy required to increase the temperature of 1 kg of water up to 1°C.

In the given question, since none of the option has provided this, therefore, assuming that cal and kcal are interchangeably used, the Option-A is the correct answer.

netineya [11]

A) Hypertonic environment

B) Lower pH

C) Depletion of nutrients

D) Lower osmotic pressure

Answer:

A) Hypertonic environment

Explanation:

A hypertonic environment or solution contains more solute than solvents, that is, the solution in the environment has more dissolved particles, such as salt or sugar. Microorganisms are unlikely to survive in a hypertonic solution as water would be drawn out of the ells of the mircoorganisms, causing their cells to shrink.

Salts and sugars are used in preserving foods as they create a hypertonic environment that is unfavorable to bacteria and fungi that cause food spoilage.
