Melting is an endothermic change, because ice absorbs energy from its surroundings as it melts.

Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Sublimation is a phase change in which a solid moves directly into the gas phase. Both melting and sublimation are two types of physical change.
Is it true that the net force acting on an object is equal to the rate of change of its momentum?
Yes, that's a true statement.
What is a true statement about stormy weather?
Conditions will change. Each storm has a finite duration.
What is one statement about nuclear energy that is not true?
It is not true that: Carbon dioxide is produced during nuclear reactor operation or during nuclear fission.
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
What is a true statement about the conservation of energy?
Energy can neither be created nor destroyed, but it can be made to change forms.

With the statement is true about energy consumption in the united states?
Which of these statements is true about energy consumption in the United States? A+:)
True or false the sublimitation is a change from solid to gas?
That statement is true.
During which phase change requires water is the most energy released into the environment?
Going from gas phase directly to solid state will conserve maximum energy. Just the opposite of the statement above will be true for maximum energy release. Changing from solid to directly into gas is called sublimation.
What is ALWAYS true about the temperature of a substance during a phase change?
Its constant (more-or-less, since energy is used in changing state rather than increasing temperature)
Electron X can change to a higher energy level or a lower energy level Which statement is true of electron X?
Electron X absorbs energy when it changes to a higher energy level. Electron X absorbs energy when it changes to a higher energy level. It takes energy to do that.
What statement is true about catabolic pathways?
The supply energy in the form of ATP

Matter and energy are equivalent (E=MC2).
What is true statement about matter?
Matter and energy are equivalent (E=MC2).
What is a true statement about matter?
Matter and energy are equivalent (E=MC2).
Is it true that in an exothermic change energy is absorbed?
No. Energy is released
