How much heat energy in kilojoules is liberated by cooling 62 g of lead from 99.1 degrees Celsius to 24.3 degrees Celsius? (specific heat of lead = 0.130 J/g degrees Celsius)

The mountains are calling me home.

 
wow... it hurts my brain to read that

actually not really, i could do it if i really wanted to, but figure it out yourself. your in the class... i'd be worried if you couldn't figure this one out.

 
then plug in the numbers cock bite

Life is tough. Its tougher when you're stupid

my school mates always said that they would fuck anything that could walk. i never saw why i had to limit myself.
 
that is probably the easiest heat transfer problem ever

if you cant figure that out your pretty damn screwed in the class.

wow that's the easiest chem question i have ever seen i wish we had had stuff like that, all u have to do is plug those numbers into q=mcΔt

you're joking right. i just want to know why you are doing such basic problems so late in the year. this is the kind of problems you d when you first learn what a calorie is.

dude just figure out that all you ever have to do is look at formulas and then set up equations in a way that manipulates the units so that you have the correct kind for your answer. then, as long as you can add, subtract, multiply, and divide, you will own quantitative chem.

I just got a 100% on my chem exam... I'm in high school though so it's mad easy. If you know the formula why are you asking how to do it? My god.

 
Yea we did that shit hella early. Read you book cock massager.

how 'bout we dig a cave that goes underneath the huge booter on Nick's run so that we have a place to puff puff-NosNjection

:please:
 
You kids must be very young, this shit took me all of 1 minute to figure out:-

q = m * c * (Tf - Ti)

where: q=joules , m=grams , c=J/g*C , T=celcius

q = 62 * 0.130 * (24.3 - 99.1)

q = -602.888 J

q = 0.60 KJ (with appropriate significant figures)

that shit is covered in both physics and chem. and it's really fucking easy and you should feel like a complete moron for not figuring it yourself. i'm not usually a mean person, but you're stupid and will most likely fail your chemistry class.

 
you yeah, I forgot to say that the value is negative because the heat is being lost (liberated) That's why my value in KJ no longer has the negative value. Because there, you state that it is lost.
