Answer:
Work = Path function.
Energy = State function.
Distance traveled = Path function.
Enthalpy = State function.
Heat = Path function.
Explanation:
Hello,
At first, a state function is a property whose value does not depend on the path taken to reach that specific function or value, as in this case, energy and enthalpy.
On the other hand, path functions are functions that depend on the path taken to reach that specific value, as in this case, work, distance traveled and heat since different paths will provide different values for each one of them.
Best regards.
Explanation:
Gases: more space therefore meaning that particles in the gas have the highest Kinetic energy therefore moving faster all around.
Liquid: they have more kinetic energy than liquid,but they have some space for movement so they collide each other quicker due to lack of space.
solids: They have least kinetic energy as they have no space at all meaning particles can move around and only just vibrate against each other.
Answer:
= 9,593.1 Joules
Explanation:
Heat absorbed by water is equivalent to heat released by copper.
Heat absorbed is given by;
Q = mcΔT
where m is the mass, c is the specific capacity and ΔT is the change in temperature.
Therefore;
Since dnsity of water is 1 g/mL, and specific heat capacity is 4.18 J/g°C while the change in temperature is (75-24) = 51°C.
Heat absorbed by water = 45 g × 4.18 J/g°C × 51
= 9,593.1 Joules
Therefore, the heat released by copper is 9,593.1 Joules
