Which of the answer choices is a true statement about the properties of an enclosed gas?
(Select all that apply)
if a gas pressure remains constant, then increasing the temperature of a gas will increase its volume
if the gas temperature remains constant, then increasing the volume will increase its pressure
if the gas temperature remains constant, then increasing the volume will increase its pressure
if a gas volume remains constant, then increasing the temperature of a gas will increase its pressure
please help
PV/T = constant.
As pressure increases, volume decreases
As volume increases, pressure decreases
As temperature increases pressure increases
As temperature increases volume could increase, but this is a closed system.
I like the last choice.
To determine which of the answer choices are true statements about the properties of an enclosed gas, we need to understand the relationships between pressure, temperature, and volume.
1. Boyle's Law states that if the gas temperature remains constant, increasing the volume will decrease its pressure. This means that the second statement "if the gas temperature remains constant, then increasing the volume will increase its pressure" is false.
2. Charles's Law states that if a gas volume remains constant, increasing the temperature of a gas will increase its pressure. This means that the fourth statement "if a gas volume remains constant, then increasing the temperature of a gas will increase its pressure" is true.
3. The Combined Gas Law combines Boyle's Law and Charles's Law and states that if a gas pressure remains constant, increasing the temperature of a gas will increase its volume. This means that the first statement "if a gas pressure remains constant, then increasing the temperature of a gas will increase its volume" is true.
Therefore, the correct answer choices are:
- if the gas pressure remains constant, then increasing the temperature of a gas will increase its volume
- if a gas volume remains constant, then increasing the temperature of a gas will increase its pressure
A group of students hypothesize that the amount of alcohol produced during fermentation depends on the amount of glucose that yeast are supplied with because glucose is required for yeast to produce energy in the form of ATP when oxygen is in limited supply. They perform the experiment using 0.5 grams of yeast in a 500 mL solution of one of the following glucose solutions: 5%, 10%, 15%, 20%, 25% and 30%.
True/False: A 0% glucose solution would serve as a good control for this experiment.
Question 3 options:
A study was designed to determine whether infants who are breast fed have higher iron levels than those who are not. To do this, researchers measured the iron levels of infants who were breast-fed and infants who were fed standard baby formula without any iron supplement. Iron levels were measured at 12 months of age. What is the independent variable?
