Explanation:
Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.
As relation between kinetic energy and temperature is as follows.
K.E =
So, with increase in temperature there will also occur an increase in kinetic energy which leads to an increase in thermal energy of the substance.
Therefore, we can conclude that by applying heat, Bela increased the thermal energy of the eggs. She could measure how much the temperature increased with a thermometer.

Explanation:
The given reaction will be as follows.
So, equilibrium constant for this equation will be as follows.
As it is given that concentration of all the species is 2.4. Therefore, calculate the value of equilibrium constant as follows.
=
= 0.173
Thus, we can conclude that equilibrium constant for the given reaction is 0.173.
Answer:
The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.
Explanation:
4% acetic acid by mass means that 4 gram of acetic acid in 100 g solution.
Given that density of the vinegar is same is that of water = 1 g/mL
Mass of the vinegar solution = 100 g
Volume of the vinegar solution = V
V = 100 mL = 0.1 L
Moles of acetic acid =
The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.
