Ahot copper pipe is placed in a water-filled calorimeter and the calorimeter is sealed. which pieces of data must you know in order to calculate the thermal energy released as the pipe cools?

mass of water, specific heat of water, temperature change of water

enthalpy of copper, mass of copper, temperature change of copper

mass of water, specific heat of water, specific heat of copper

enthalpy of water, temperature change of water, mass of copper

The correct answer is A: mass of water, specific heat of water, temperature change of water

Explanation:

I just finished this quiz.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied

the answer is symmetrical : )
