The heat energy needed to raise the temperature of vapor above its saturation point is called _____________________. A. sensible
lana [24]

Answer:

Option (D)

Explanation:

The super-heating is usually defined as a phenomenon where a certain amount of energy is needed to raise the temperature of the water vapor beyond its normal saturation point. This is also known as the boiling delay.

The super-heat can be mathematically written as:

Super-heat = Current temperature - Boiling point of the liquid.

Thus, super-heat refers to the amount of energy that is required to increase the temperature of vapor beyond its point of saturation.

This super-heat is essential as it helps in preventing the damages of machines like air conditioner, fridge and also helps in their soft running.

Hence, the correct answer is option (D).

What is the mass of 4.38 x 10^24 formula units of sodium chloride (NaCl)?
lana66690 [7]

Answer:

Mass = 427.05 g

Explanation:

Given data:

Formula units of sodium chloride = 4.38 ×10²⁴

Mass of NaCl = ?

Solution:

One mole contain formula units = 6.022 ×10²³

4.38×10²⁴ formula units × 1mol /6.022 ×10²³ formula units

0.73 ×10¹ mol

7.3 mol

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 7.3 mol × 58.5 g/mol

Mass = 427.05 g
