Difference between sensible heat and latent heat?
Sensible heat is heat supplied or taken away and causes an immediate change in temperature without changing the state. While latent heat is heat supplied or taken away and causes a change in state without change in temperature. This difference can be applied to the certain properties of water/steam. This is called the thermodynamics properties of steam.
Which heat changes the state of a substance without changing its temperature?
both the heat of fusion and the heat of vaporization
How can temperature be increased without heating?
It is possible to add heat to a substance without changing its temperature. That happens during melting and boiling. However, I cannot think of a case in which the temperature of a substance increases without heat being added to it, either by radiation, conduction or convection.
What will change the density of an object?
Either a decrease or increase in temperature will change the density of an object.
Why considerable heat energy is needed to convert 1g of water into 1g of steam at 100c without any change in temperature taking place?
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
Can proteins absorb or lose heat without changing temperature?
No, proteins can't absorb or lose heat without changing much in temperature. Water has a high heat capacity, so water can absorb or release a great deal of heat energy without changing much in temperature.
Rocks can melt without changing temperature when the pressure exerted on them is .?
Increase
When can voltage be induced but not current?
"Induced" is the verb you are looking for. A current is induced in the secondary circuit by the current in the first changing, provided both conductors are close enough for the driving current's electro-magnetic field to enclose the second conductor. Note that word "changing". Direct current produces a field but that remains constant and does not induce a secondary current, as a.c. does.

How can you decrease the pressure of gas in a container without changing the volume of the gas?
You could lower the temperature.
Can you increase current in a circuit without change in resistance and voltage?
no it is not possibleAnswerYes, by changing the voltage OR the resistance.
What is the energy required to change a substance from a solid to a liquid WITHOUT changing it's temperature?
magic of coarse!
What could you do if you wanted to reduce the volume of gas without changing the temperature?
You could let the gas flow !
What energy is required to create a phase change without changing the temperature?
It is called the latent heat of vaporisation.
Which heat changes the state of a substance without changing its temperature?
both the heat of fusion and the heat of vaporization
How do you make ice last longer in a cup without changing the temperature?
you put it in a refridgerator or a cooler which ever works for you
