Question

The specific heat of gold is 130 C/kgK. How much energy would be required to raise a 200 gram piece from 22 deg C to 30 deg C?

Answer 1

here we have to apply the subsequent formula:
\[\Large Q = cm\Delta t = 130 \times 0.2 \times \left( {303 - 295} \right)\]
since 22 °C degree coreepsonds to 295 K
and
30 °C degree corresponds to 303 K

Answer 2

200 grams corresponds to 0.2 Kg

Answer 3

ok! and so we get 208?

Answer 4

yes! and the right unit of measure is Cal or Kcal
namely we have:
208 C or 208 Kcal

Answer 5

ohh ok! yay so that is our solution? :O

Answer 6

yes!
