Answer: Option (c) is the correct answer.
Explanation:
Entropy is defined as the degree of randomness. This means that more is the number of collisions taking place between atoms of a substance more will be the randomness.
Therefore, more will be the entropy of substance. We cannot measure the entropy but we can measure the change in entropy of a substance.
A thermometer is a glass tube that contains a liquid column generally mercury, and it is usually used to measure the temperature of human body.
A calorimeter is a device or apparatus that is used in a chemical reaction to measure the amount of heat involved.
Therefore, we can conclude that the student can't measure entropy directly, only an entropy change.
The answer is Sulfuric acid
Answer: So you could for example say, “IF I through my clothes into the closet. THEN the floor will be visible” I capatlized if and then because you need them in a hypothesis.
Explanation:
I think the answer is a molecule
Question is incomplete, complete question is :
A fixed quantity of gas at 21°C exhibits a pressure of 758 torr and occupies a volume of 5.42 L .
Calculate the volume the gas will occupy if the pressure is increased to 1.89 atm while the temperature is held constant.
Answer:
The final volume of the gas will be 2.86 L.
Explanation:
initial pressure of the gas =
initial volume of the gas =
Final pressure of the gas =
Final volume of the gas =
Applying Boyle's law;
( at constant temperature)
The final volume of the gas will be 2.86 L.
