CHEMISTRY HELP NEEDED!

1) An 85.0 g sample of copper is initially at 22.2 ∘C What is the final temperature if the sample absorbs 2.35 kJ of heat?

The specific heat of Cu is 0.385 J/(g^ Degree C)

2) A 75.0 g sample of aluminum is heated to 65.3 ∘C then allowed to cool. What is the final temperature if the sample releases 2.07 kJ of heat?

The specific heat of Al is 0.903 J/(g degree C)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

c) should be the answer.

ok whats the question if not i cannot you i need question and need a thing to answer
