Answer:The constituents of the mixture can be separated by physical methods. Boiling point and the melting point of the mixture depends upon the characteristic of the constituents. During the formation of a mixture, there is no change in the energy. All the states of matter (solid, liquid, gases) can combine to form mixtures.
Explanation:
The new volume of the soccer ball is 9 litres when temperature inside the can was 25°C and pressure remained constant.
Explanation:
Data given:
initial volume of the ball, V1 = 3.6 litres
temperature of the field, initial temperature, T1 = 10°C
temperature in the trash can, final temperature, T2 = 25 °C
pressure =constant throughout
volume of the ball when in trash can, final volume V2 =?
From the data given:
Charles' Law will be applied to know the volume of the ball in the can:

putting the values in the equation after rearranging it:
V2 = 
V2 = 
V2 = 9 litres
The volume will be increased to 9 litres when ball will go inside the trash can.
The normal boiling point<span> of </span>ethanol<span> is 78.4 degrees C and, at thistemperature, </span>the vapor pressure<span> is 101325 Pascals (Pa) or 760manometric units
thx hope this helped bye.</span>
