Answer:
212 degrees F, and 100 degrees C.
Explanation:
If the temperature is held constant (which requires some heat input, since evaporation cools things) the liquid will all evaporate. If the temperature is much above 212 F, the water will boil. That means that it wont just evaporate from the surface but will form vapor bubbles, which then grow, inside the liquid itself. :)
No.of moles of N2O= 0.221g/(14*2+16) =0.005022727moles
no.of moles of N = 0.005022727*2 =0.010045454moles
Explanation:
Speed and velocity are both used to describe the motion of a body. But there are differences between the two terms.
- Velocity is the rate of change of displacement with time. It is mathematically expressed below:
Velocity = 
The unit of velocity is m/s or km/hr.
Velocity is a vector quantity that shows magnitude and direction.
- Speed is the rate of change of distance with time. It is concerned with the total length of path a body moves.
Speed = 
It has the same unit as velocity
It is a scalar quantity that has only magnitude.
