What is the Final Temperature given Heat (q=mcΔT)

- Опубликовано: 28 июн 2018
- You can calculate delta T, ΔT, using the formula q/(mc).
Then, if heat was absorbed by the substance, you know the temperature went up, and so you ADD delta T to the initial temperature.
If heat was released by the substance, you'll need your final temperature to be LOWER than your initial one. Half of kids use a negative Q (heat) which gives them a negative ΔT, which is ideal. The other half of kids forget that negative, but then they SUBTRACT the delta T from the initial temperature. That's fine too.

your channel is small but do not let this limit you from doing great things. I am so appreciative to come across this channel! Please keep it up!
Where are you nate?😓😓😓Please come back!! We need you here😭😭😭

Thank you for all of these examples!!!
You helped me out so much, I spent two days trying to understand why none of my answers were correct. Turns out I didnt add open brackets!! Definitely subscribing💛
I Have a test today and this was so helpful! Thank you so much !!!!
This is so helpful.Thanks
I also have a request to make.
Can you do a video on the exceptions of trend in ionization energy electron affinty and atomic radius...It'll be better to know all the exceptions at once...and yeah melting and boiling point exceptions as well
@Jm Cresencio Thanks alot but I dont need it anyomre😂😂😂...I needed this for my entry test and I just gave it a week ago and the chem portion was easy but I fucked up the phy portion...Now I'm waiting for official result..Its gonna decide weather I'll be a doctor or not...I'm afraid..plz do pray for me if you have time

PLEASE!!! I NEED SOME HELP!!
What is the new temperature ( C) of a 2.75 kg aluminum camping dish if it was heated from 24.7 C by 77.1 kJ of heat.
At a village a mother heats 4 liters of water with a paraffin stove from a temperature of 18 °C. She later noticed that 20 g of the paraffin was used up. Calculate the final temperature of the water if the heat value of paraffin is 31 MJ/kg and the specific heat capacity of water is 4187 J/kg. °C.
Pls help solve this
Thank you 🤧❤️❤️
Ty
Thanks

Oo
DO A FACE REVEAL!!!!!!!!!!
@Andre Haha he's my math teacher
damn I just took an exam and I subtracted delta T from the initial!!!!!!!😫😫😫
and it was positive!!!!
