A 500 g bar of copper (c = 387 P/kgoC) at 20.0 oC has 10,050 J of heat removed

from it. What is its final temperature?

The final temperature is 71.94 °C

Explanation:

Step 1: Data given

Mass of the copper bar = 500 grams

The specific heat of copper = 387 J/kg°C = 0.387 J/g°C

The initial temperature = 20.0 °C

Heat removed = 10050 J

Step 2: Calculate the final temperature

Q = m*c * ΔT

⇒with Q = the heat removed = 10050 J

⇒with m = the mass of the barr of copper = 500 grams

⇒with c= the specific heat of copper = 0.387 J/g°C

⇒with ΔT = the change of temperature = T2 -T1

10050 = 500 * 0.387 * ΔT

ΔT = 10050 / (500*0.387)

ΔT = 51.94 °C

Step 3: Calculate the final temperature

ΔT = T2 - T1

⇒with ΔT = the change of temperature = 51.94 °C

⇒with T2 = the final temperature = TO BE DETERMINED

⇒with T1 = the initial temperature = 20.0 °C

51.94 °C = T2 - 20.0°C

T2 = 51.94 °C + 20.0 °C

T2 = 71.94 °C

The final temperature is 71.94 °C

what is the question?

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
