I'm from Jamaica and I have exams tmr and I never understood latent heat or specific heat capacity but this video and brian helped me a lot and now I am more confident that I will pass my exams...I am looking forward to watching the maths videos.

Glad it helped and best wishes for the exams!!

The answer was supposed to be 1277525 J or 1277.525 if you add all of them. I was confused for a second there.

Perfect, short, sweet, and to the point.

Well explained 👏🏽. Now , can this concept be use to explain why it is easier to distill a solvent such as Toluene compared to water, considering the fact that Toluene has a higher boiling point than water?

Thank you for this!!

@@stepbystepscience doctor is it possible for you to solve a few more questions that has a unique way to solve? For example, not having a mass not density but having a volume, or dropping an object into water, you know those vary kinds of questions. This would be so helpful and appreciated and i will make sure to share it to all my classmates.

Im wondering where did you get the 10^3?

@stepbystepscience

Жыл бұрын

Because it is 333 kJ (kilojoules) but when you put the number into the equation it has to be in regular joules and not kilojoules. So the 333kJ can be written as 333,000 J or 333 x 10^3 J. Does that help?

very good sir

In the Rankine steam power plant, 2 kg of steam at enters the condenser. Determine the amount of heat rejected by the steam in the condenser to change its phase from vapor to liquid in an isothermal process. Take the latent heat of vaporization of water is 2260 kJ/kg. Please help solve this

what would happen if you reversed the equation so that i would be able to use it to find the energy transferred away from 100g of steam @ 100 degrees to change it to a liquid?
