Question

Angie is warming up a piece of copper for a calorimetry experiment. She has found the mass of her piece of copper to be 30.96 grams and its initial temperature is 5.6 degrees Celsius. Angie needs the copper to be at 151 degrees Celsius for her experiment. How much heat must the copper absorb so that Angie can do her experiment? Please round your answer to one digit after the decimal point. Metal Specific Heat (J/gC) Lead 0.128 Silver 0.233 Copper 0.386 Aluminum 0.900

Answer 1

Q = 1737.61J

Step-by-step explanation:

Mass of copper = 30.96g

Initial temperature (T1) = 5.6°C

Required temperature or final temperature of the metal (T2) = 151°C

Specific heat capacity of copper = 0.386J/g°C

Heat energy required (Q) = ?

Heat energy (Q) = mc∇T

Q = heat energy

M = mass of the material

∇T = change in temperature = T2 - T1

C = specific heat capacity of the material

Q = mc∇T

Q = 30.96 * 0.386 * (151 - 5.6)

Q = 11.95056 * 145.4

Q = 1737.61J

The energy required to heat up the metal is 1737.61J
