A 1.5 m3 tank contains 500 kg of liquid water in equilibrium with pure water vapor, which fills the remainder of the tank. The t
emperature and pressure are 100°C and 101.33 kPa. From a water line at a constant temperature of 70°C and a constant pres- sure somewhat above 101.33 kPa, 750 kg of liquid is bled into the tank. If the temper- ature and pressure in the tank are not to change as a result of the process, how much energy as heat must be transferred to the tank?

Answer:
22.2 m/s
Explanation:
First, we need to convert km to m by multiplying by 1000. This means that the car traveled 320 000 meters.
Next, we convert hours to minutes by multiplying by 3600 (the number of seconds in an hour). This means that overall, the car traveled 320 000 m in 14 400 seconds.
The average speed can be found by using the equation . After substitution, this gives the fraction
, which reduces to 22
m/s, or about 22.2 m/s.
