A sample of gas occupies 17 mL at -122°C. What volume does the sample occupy at 70°C?
aev [14]

Answer: 38.6 ml

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.


V\propto T    (At constant pressure and number of moles)

\frac{V_1}{T_1}=\frac{V_2}{T_2}

V_1= initial volume = 17 ml

V_2= final volume = ?

T_1= initial temperature =-122^0C=273+(-122)=151K

T_2=final temperature=70^0C= 70+273=343K

\frac{17}{151}=\frac{V_2}{343}

V_2=38.6ml

Thus final volume is 38.6 ml at 70^0C

Matter has mass and takes up ______________. The amount of space that matter
svlad2 [7]
Answer:
space

Explanation:
Matter possesses mass and occupies space around it. The space is measured using the property known as volume. Different states of matter occupy spaces in different ways depending on how big, small, rigid, flowing etc. they are. Hence, each state of matter appears a bit differently and they have different volume.
