Answer:
If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase. ... Gay-Lussac's law states that at constant volume, the pressure and temperature of a gas are directly proportional.

Answer:
121.63 g/mol
Explanation:
Sr(OH) 2 = Strontium Hydroxide
To calculate atomic mass, you have to take to weighted average of the isotopes' masses. What that means is M = RA*106 + (1 – RA)*104, where RA is relative abundance expressed in decimal form. If you simplify the right side of that equation, you get M = 2*RA + 104. Doing a little more algebra yields RA = (M –104)/2 = (104.4 – 104)/2 = 0.4 / 2 = 0.2, which is 20%. So the answer is B.
Answer:
<em>a) The variable that we will change will be the different liquids.</em>
<em>b) The variable which will be kept same will be the ramp angle, the time for measuring in each experiment and the heat. </em>
Explanation:
In a scientific experiment, an independent variable is a variable which is changed by the researcher so that its effect on the dependent variable can be studied.
A dependent variable is a variable which is under study and might be influenced by changes in the independent variable.
It is best to study the effect of a single independent variable at a time so that we can easily infer the results.
<u><em>In the scenario discussed in the question, we would change the different liquids so that the time taken by each liquid to flow down the ramp can be studied.</em></u>
<u><em>We will keep the ramp angle, the time (of each experiment) and heat for each of the experiments the same so that a just conclusion can be drawn.</em></u>
