Absolute Zero
« on: September 23, 2007, 03:16:35 PM »
Calculate absolute zero on the Fahrenheit scale to the greatest number of significant figures allowed.


My answer was –459.67 °F but i was told that this is incorrect! What's the real answer, anyone?
Isn't absolute zero (0 Kelvin) ?

Absolute Zero= 0 Kelvin

Deg F = (deg K - 273.15) * 9/5 + 32 = –459.67 °F

Seems OK to me - unless you are expected to add infinite number of zeros, as -459.67 is an exact value

I am not sure though, second opinion won't hurt.

What do you mean by infinite numbers of zeros? What would it look like?

Do you think the significant figures are right?

^^ forgot to post my answer.. -460 degrees F. Wouldn't it be 3 sig figs according the the equation.
