Answer:
FALSE
Explanation:
Assuming that the gas is ideal
Therefore the gas obeys the ideal gas equation
<h3>Ideal gas equation is </h3><h3>P × V = n × R × T</h3>
where
P is the pressure exerted by the gas
V is the volume occupied by the gas
n is the number of moles of the gas
R is the ideal gas constant
T is the temperature of the gas
Here volume of the gas will be the volume of the container
Given the volume of the container and number of moles of the gas are constant
As R will also be constant, the pressure of the gas will be directly proportional to the temperature of the gas
P ∝ T
∴ Pressure will be directly proportional to the temperature
If iron atom looses 3 electrons, it forms Fe+3 (ferric) and if iron looses 2 electrons, it forms Fe+2(ferrous). Hope this helps!
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).
