<span>The function of a hypothesis is to create a testable statement. In that, a hypothesis can be followed up by a experiment. Hypotheses can be used in order to determine if there is a result of an affect, this is the independent variable, what you get out is the dependent variable, or the result. There is a control that is used generally as a means to test your hypothesis to a standard.</span>
Answer:
The correct answer is 3.6 L
Explanation:
According to the gases Boyle's law, the relation between the volume and the pressure of a gas at constant temperature is given by the following mathematical expression:
Pi x Vi = Pf x Vf
Where Pi and Vi are the <u>initial </u>pressure and volume of the gas whereas Pf and Vf are the <u>final</u> pressure and volume, respectively.
In this problem we have:
Vi = 18.0 L
Pi= 902 Torr
Pf= 4510 Torr
The final volume (Vf) will be:
Vf = (Pi x Vi)/Pf = (902 Torr x 18.0 L)/4510 Torr= 3.6 L
From the result, we can see that if the pressure increases, the volume of the gas decreases.
Answer:
The reaction is endothermic
Increase temperature of the flask
Explanation:
Sublimation is a phenomenon in which a substance changes directly from solid to gas,without passing through the liquid phase.
Camphor is a sublime substance. The sublimation of camphor is an endothermic reaction. This implies that energy is absorbed in the process.
For an endothermic reaction, the equilibrium position is shifted towards the right hand side by increasing the temperature of the system. Hence, if the flask is heated, more camphor will condense within a shorter time interval.
