What do thermal insulators have
Thermal insulators have insulating capabilities. This means that
they do not have any aspect that allows them to conduct thermal
energy.
When baking soda is mixed with vinegar which type of reaction has taken place
Solid metals undergo greater thermal expansion than liquids do
Liquids have higher coefficients of expansion than solids do in general
A horizontal line on a phase-change graph indicates
The temperature of an object is a measure of the average thermal energy of the molecules in the object
Swamp coolers are effective because
the water's latent heat of vaporization is being pulled from the
air, the water pulls heat from the room to undergo a phase
change.
The of an acid and a base is determined by how completely they dissociate in water
The _____________ of an acid and a base is determined by how
completely they dissociate in water.
strength
On a cold winter day the flow of heat is from the outside in
A horizontal line on a phase change graph indicates
A horizontal line on a phase change graph means there has been
no change. Often longer periods of research are needed to see
significant change.
The sum of the kinetic energies and potential energies of all of in the molecules in a substance is called the what energy of the substance
What temperature Fahrenheit and celsius thermometers would read as the same number
Is the temp of an object a measure of the total kinetic energy of molecules in the object or a measure of the average kinetic energy per molecule in the object
When a substance goes directly from a gaseous state to a solid state as dry ice does what
What is it called when one or more substances change into one or more new substances
This is a chemical reaction.
What substance below requires the most energy to raise its temperature by 7 degrees C
