Answer:
q(ice) = -q(warm water)
Explanation:
Ice removes energy if ice is put in warm water and ice retains the very same amount of energy. Thus the water temperature heat sign is negative, and the ice heat sign is positive.
If your talking about the chemical equations like combustion, single displacement, etc. Then the equation would be double displacement:
AB + CD ---> AD + CB
Answer:
nothing, mass is not affected by gravitational force
Explanation:
Weight is the gravitational force a planet exerts on a mass on the surface.
It is the product of the mass of an object with the gravitational acceleration that the planet produces.
The weight is the gravitational force
where,
m = Mass of the object
g = Acceleration due to gravity = 9.81 m/s²
Mass is the property that matter has which opposes the force being applied to it. It is intrinsic to the object itself and does not change according to the gravitational force. But, the weight changes.
