Homework Help: Find the final temperature of the ball

  1. Nov 22, 2004 #1
    A copper ball with a radius of 1.5 cm is heated until its diameter has increased by 0.20 mm. Assuming a room temperature of 22°C, find the final temperature of the ball.

    What have you tried?

    well, I know that the coefficient of linear expansion for copper is 17 x 10^-6, so it's coefficient of volume expansion is 3 times that.. and I know that the volume has changed by about .54. I'm not really sure what to do with this though

    I assume I'm using the equation delta V = BV(delta T), but when I do this I get a huge number

    nevermind, I got it. I was subtracting 22 instead of adding it. The answer is 410.27 right?
