Answer:
single replacement
Explanation:
In the question it says one element replaces another element which means there is only one replacement.
Given mass= 1kg
Weight on earth = mg(gravity of earth) = 9.8N
weight on moon = mg(gravity of moon)= 1.62N
weight on outer space mg(gravity outer space = 0) = 0N
Answer:
46.9 C
Explanation:
The heat released by the gold bar is equal to the heat absorbed by the water:
where:
is the mass of the gold bar
is the specific heat of gold
is the initial temperature of the gold bar
is the mass of the water
is the specific heat of water
is the initial temperature of the water
is the final temperature of both gold and water at equilibrium
We can re-arrange the formula and solve for T_f, so we find:
