Question

Please help !!!!!

Calculate how many joules of energy are needed to warm 4.37 g of silver from 25.0C 27.50 if the specific heat of silver is 0.24 J/g C?

Answer 1

Step-by-step explanation:

warm up 2.5C

mass 4.37

specific heat 0.24

energy = 2.5*4.37*0.24

= 2.6J

Answer 2

Step-by-step explanation:

Energy needed = mass * temperature difference * specific heat

= 4.37 * (27.5-25) * 0.24

= 4.37 * 2.5 * 0.24

= 2.622J
