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)

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.

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.
