How does the temperature of a substance change as it gains or loses heat?

∙ 14y ago
A substance (in this case water) that gains or loses 'sensible' heat will change it's temperature at the rate of 1 deg F per pound of that substance per 1 btu loss or gain.
That is to say that 1 pound of water will change 1 deg f as it loses or gains 1 btu of heat energy. That heat required to lose or gain 1 deg f is referred to as sensible heat, whether lost or gained, since it does change the temperature of the substance.
However, that substance must gain or lose latent heat during a change of state; as in water changing from liquid to gas (steam). Latent heat affects the substance during it's change of state, and does not change the temperature of the substance during that change of state.
Each substance has a specific heat, and so each substance has a different value of btu's required to make a change in their state or temperature.

∙ 14y agoHeating means that the temperature of that particular substance is increasing. While a substance may transit from solid state to liquid state, it is not necessary that it's temperature will rise... the energy that is being absorbed will be rather utilized for loosening the intermolecular bonds..... excess of energy, however, will raise the temperature. (you may look for latent heat)

A material has a net charge because it?
A net charge results when an atom gains or loses electrons. If it loses electrons, it gains a positive charge, if it gains them, it gains a net negative charge.
When an atom loses or gains it becomes a?
Ion
What does an object get when it gains or loses electrons?
electric charge
When atoms loses or gains electrons it becomes a?
An ion.
What is an atom that gains and loses an electron and has an electric charge?
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
When a substance loses or absorbs energy its temperature can change true or false?
Very true.
Does Static charge develops on a substance as it acquires or loses protons due to friction?
False - A substance gains or loses ELECTRONS, no protons.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.
When a substance changes from one state to another it gains or loses?
energy
Does melting lose or gain temperaturre?
loses When ice melts it gains heat. The environment, however, loses heat. So what does heat have to do with temperature? Often they vary in the same direction; temperature has been likened to the average kinetic energy of the substance. Melting typically ( e,g,, for ice-water) clamps the temperature at a constant value, but heat flows into the substance that melts.
Is the change in mass significant when an object gains or loses electrons?
no
When an atom gains or loses a valance electron does it have a physical or chemical change?
That is a chemical change.
Definition of percent of change?
Percent change is the extent to which something gains or loses value.
Simple explanation of what is an electrolyte?
An electrolyte is a substance than gains or loses electrons when dissolved in a solvent.
Does water change its temperature easily?
No it doesn't. Water has a very high heat capacity so it both gains and loses heat slowly compared to many other substances.
When do two objects have the same temperature?
one object loses energy then the other one gains energy.
what is the chemical change when a substance loses its luster?
Probably oxidation.
