Intensity:
How hard you work during the session

For cardio : workout at your target heart rate.
For HIIT: varying intensity from high to low or rest ( no slow pace)
For strength: you should lift enough weight to complete the needed number of reps and sets.

Time:

For cardio 30- 60 min
For HIIT 45 min (short periods of bursts followed by rest)

For strength depends on the amount of weight.

A gas has a volume of 60dm³ when it is under a pressure of 30kpa. Calculate it's volume when pressure changes
vesna_86 [32]

Explanation:

Given that,

Initial volume = 60dm³

Initial pressure = 30 kPa

We need to find the new volume when pressure changes to 40 kPa (say).

We know that the mathematical relation between volume and pressure is given by :

\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}

Put all the values,

V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{30\times 60}{40}\\\\V_2=45\ dm^3

So, when pressure of the gas increases, its volume get decreased.
