Volume remains constant: P1 x T2 = P2 x T1. Pressure increases in direct proportion to absolute temperature increase.
<span>203kPa x 273K = P2 x 203K = P2 x 55,419. </span>

A condenser is laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down. Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction(Wikipedia).
Condensers of of practical importance especially in synthetic organic chemistry and in separation science where vapours are often condensed and collected the substance is collected in pure form by distillation.
The factor or condition can be changed is known as a variable. There are independent variables which are variables intentionally changed by the investigator. There are also dependent variables that can be changed as a result of the independent variable. There is also the controlled variable that can't be changed or it would ruin the experiment.
Scientists are running a test to see if eating junk food makes mice gain more weight than the Mouse Chow.
Independent variable: diet of mice
Dependent variable: weight of mice
Controlled variable: amount of food given
*Note there can be more than one controlled variable
**An independent variable is also known as a manipulated variable
***An dependent variable is also known as a responding variable
