In question 2 if all of the ice has melted then why it isn't the mixture temperature is 0°c ?

For problem 2, it's much easier to solve algebraically first. It looks daunting because I've included extra steps for clarity and review. Most people will be comfortable jumping from 1 to 3 and then 3 to 5. It takes a minute. Doing the algebra first this way helps you spot any errors in unit analysis at the end and means you just have to move symbols, rather that keep track of numbers. If this helps you great. If it looks too scary then you should do this more until it's second nature. q1+q2+q3=-q4 "mi" is the mass of ice. "ci" is specific heat of ice. "mw" for water. "cw" for water. *NOTE* q3 considers the mass of ice, but _in liquid, or water, form._ This is because this term accounts for the grams of ice that have gone through fusion, and while they are zero degrees C, these grams are now liquid water.* 0. begin by setting up. Remember you negative sign! micidTi + midH + micwdT = -mwcwdTw 1. dT equals Tf minus T initial micidTi + midH + micw(Tf - 0) = -mwcw(Tf - #) 2. Distribute masses and specific heats micidTi + midH + Tfmicw - -0xmicw- = -Tfmwcw + #mwcw 3. anything times zero is zero, so ^ term goes away. Also pay attention to the negative and rearrange. #mwcw - micidTi - midH = micwTf + mwcwTf 4. Factor out what you can to simplify #mwcw - mi(ciTi - dH) = Tfcw(mi + mw) 5. Divide through by "cw(mi + mw)" Tf = (#mwcw - mi(ciTi - dH))/cw(mi + mw)

Thank you so much for providing examples for both situations, my professor skipped over this but assigned it for homework. I was very lost to say the least but I stumbled upon your video and you explained and walked through the process very beautifully! Thank you! After struggling on this question for over an hour now, I was able to complete it in 15 minutes!

Given the specific heat of water is 4,186 Jkg 1 °C*1, specific heat of milk is 3,830 Jkg ' °C*', specific heat capacity of ice is 2, 100 Jkg 1 °C•1 and latent heat of fusion of ice = 330,000 Jkg*-1

@davidellis7183 5 жыл бұрын

sorry for the lame question, but I can never understand why you use the same specific heat capcity of 4.18 ( instead of 2.11 specific heat of ice ) on the left and LEFT side of the equation, when calculating iCe melting. For instance 5295+15(4.18)*(tf-0) = 250 (4.18)*(tf-90) instead of 5295+15*(2.11)*(Tf-0) = 250*(4.18)*(Tf-90)

@sassysassy9950 4 жыл бұрын

That's my problem too. Now, I'm having confusion on when to use the specific heat of water.

@heyitsznep 4 жыл бұрын

That's because the process is already converting ice to water, so, the specific heat capacity should be of water.

@senny- Жыл бұрын

You said it yourself? The ice already melted. It's water now. q1 the ice is just heating up so the c is still of ice. q3, it already melted. (It melted during q2.) q3 is you calculating the melted ice heating up even further because it's mixed with warm water.

@elie.makdissi 4 жыл бұрын

But the ice melts at a temperature above 0°C, and here the final temperature is 0°C so how the ice can melts in the 1st example?

@rodolf5941 4 жыл бұрын

q1 is for making the ice 0 celsius. And q2 is to melt the ice from 0 celsius to whatever new temperature it becomes.
