The statements that are true from the information contained in the question is;

Geologists, biologists, and physicists are only able to gather data through laboratory experiments.

Laboratory experiments are a useful form of scientific investigation in many different fields of science.

<h3>What is an experiment?</h3>

The term experiment refers to the manner in which information could be obtained. We know that we are able to arrive at new knowledge in science by conducting carefully controlled experiments. In this experiment, there must be a dependent variable as well as an independent variable.

The independent variable is the variable that we are able to manipulate in the course of the experiment while the results that we obtain when we manipulate the independent variable affects the values of the dependent variable.

Hence, the statements that are true from the information contained in the question is;

Geologists, biologists, and physicists are only able to gather data through laboratory experiments.

Laboratory experiments are a useful form of scientific investigation in many different fields of science.

Calculate the volume 3.00 moles of a gas will occupy at 24.0˚C and 1.003 atm. *
vitfil [10]

Answer: 72.93 litres

Explanation:

Given that:

Volume of gas (V) = ?

Temperature (T) = 24.0°C

Convert 24.0°C to Kelvin by adding 273

(24.0°C + 273 = 297K)

Pressure (P) = 1.003 atm

Number of moles (n) = 3 moles

Molar gas constant (R) is a constant with a value of 0.0821 atm L K-1 mol-1

Then, apply ideal gas equation

pV = nRT

1.003 atm x V = 3.00 moles x 0.0821 atm L K-1 mol-1 x 297K

1.003 atm•V = 73.15 atm•L

Divide both sides by 1.003 atm

1.003 atm•V/1.003 atm = 73.15 atm•L/1.003 atm

V = 72.93 L

Thus, the volume of the gas is 72.93 litres

Based on temperature changes, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.

<h3>What is change of state?</h3>

Change of state is the process whereby a substance changes its state of matter from one form to another as as result of heat changes.

In the graph shown above, water exists in three states at different points.

  • Water exists as a solid at A
  • Water exists as a liquid at B
  • Water exists as a gas at C.

Therefore, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.
