Is My Graph of Temperature vs. Time Correct for Heated Water with Constant Mass?

AI Thread Summary
The graph of temperature versus time for heated water with constant mass is correct as described. The temperature increases until it reaches 100 degrees Celsius, where it remains constant during the phase change from liquid to vapor. This plateau occurs because the energy supplied is used for the phase transition rather than increasing temperature. After the phase change, the mass of water begins to decrease as it evaporates. Understanding this process is crucial for accurately depicting temperature changes in heated water.

A question came for my physics exam that water was being heated and the graph showed that the mass of water remained constant from 25 degree celsius to 100 degree celsius and then started decreasing in mass. The question asked to draw a graph of temperature against time and i drew the temperature increasing for the amount of time that the mass of water remained constant. Is that correct?

Yes, what you drew was correct. The water heats to the boiling point so the temperature rises. Once 100 C is reached, the temperature will remain constant as all the energy of heating is consumed by the water changing phase from liquid to vapor.

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
