Question

A 500g glass statue is accidentally knocked from a shelf 1.5m high. If 3% of the gravitational potential energy is converted into heat, how much does the statue’s temperature rise

Answer 1

Answer:

0.0001158443168226212 Celcius (significant digits? who cares.....) or about 0.00021 Fahrenheit

Explanation:

500g=0.5kg

PE=mgh

PE=(0.5)*(9.81)*(1.5)

PE=7.36J

3% of 7.36 is 0.22J is converted to heat

From there, it's tricky.

I just used a joules to celcius converter to get 0.0001158443168226212 degrees celcius or 0.00021 degrees fahrenheit rise in temp.
