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.
What else can I help you with?
Does the rate of heating equal to the rate of cooling of a substance?
No, the rate of heating and the rate of cooling of a substance are not necessarily equal. The rate of heating refers to how quickly a substance gains heat energy, while the rate of cooling refers to how quickly a substance loses heat energy. These rates can be different depending on factors like the material of the substance, the temperature gradient, and the presence of insulation.
What does an object get when it gains or loses electrons?
When an object gains electrons, it becomes negatively charged. When it loses electrons, it becomes positively charged. This change in charge affects the object's interactions with other charged objects.
What is this change in oxidation state called?
This change is called oxidation (increase of ox. state) or reduction (decrease)
When an atom loses or gains it becomes a?
Ion
When atoms loses or gains electrons it becomes a?
An ion.
What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
When a substance loses or absorbs energy its temperature can change true or false?
True. When a substance loses energy, its temperature can decrease, while when it absorbs energy, its temperature can increase. This is because energy is transferred as heat, which can lead to changes in temperature.
When a substance changes from one state to another it gains or loses?
energy
What causes phase change's to occur?
Phase changes occur when there is a change in temperature or pressure that affects the arrangement of particles in a substance. When a substance gains or loses energy, its particles can move farther apart or closer together, leading to a change in phase (such as melting, freezing, boiling, or condensation) as the substance transitions between solid, liquid, and gas states.
How do object change temperature?
Objects change temperature through the transfer of heat energy. This can occur through conduction, convection, or radiation. When an object gains heat energy, its temperature increases, and when it loses heat energy, its temperature decreases.
A substance loses energy during what two processes?
A substance loses energy during cooling and evaporation processes. During cooling, heat is transferred away from the substance, lowering its temperature. During evaporation, the substance loses energy as molecules escape from its surface, causing it to undergo a phase change from liquid to gas.
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 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.
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.
What is the name for a substance that gains an electron or loses oxygen?
This substance is called an Oxidant or an Oxidising Agent .It oxidises the other substance and reduces itself .
