1 litre of water at 20°C will occupy what volume at 80°C? Water has a volume expansion coefficient of 210x10-6/C°​

1.031 L

Explanation:

Volume expansion is the change of volume in a change in temperature. The volume expansion is the result of energy increase of heat resulting in a separation of the spacing between the molecules. The volume expansion is proportional to the temperature change. The volume expansion is written as ΔV=VoβΔT

Where:

Vo is the initial volume,

β is the volume expansion coefficient, and

T Δ is the temperature change

The final volume in a volume expansion is

V = Vo+VoβΔT

V = ( 1.000 L ) + ( 1.000 L )( 210 × 10  ^-6 c )( 80.00∘C−20.00∘C )

V

= 1.013 L

Hope it helped :)

have a nice day

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
