True or False- Energy is transferred as heat from a substance at high temperature to a substance at low temperature?
True. Heat is transferred from a substance at high temperature to a substance at low temperature to reach thermal equilibrium.
Is energy is transferred as heat from a substance at high temperature to a substance at low temperature?
yes
Why does temperature effect the physical state of matter?
a low temperature will freeze the substance, a high temperature will melt or turn the substance into vapor
Use toxic in a sentence?
Alcohol turns into a toxic substance when consumed in high quantities.
How does specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How does the specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How does a bedbug heater effectively eliminate bedbugs from a room?
A bedbug heater works by raising the temperature in a room to a level that is lethal to bedbugs. The high heat penetrates into cracks and crevices where bedbugs hide, effectively killing them and their eggs. This method is non-toxic and can eliminate bedbugs without the need for chemicals.
How can one determine the critical temperature of a substance?
The critical temperature of a substance can be determined by conducting experiments to observe the temperature at which the substance transitions from a gas to a liquid under high pressure. This critical temperature is a key characteristic of the substance's phase behavior.
Is it true that a high temperature has particles that move quickly?
Not precisely. A temperature can't have particles. A substance which is at a high temperature has particles which are moving fast.
What happens when a ferromagnetic substance is heated to high temperature?
At a specific high temperature, called Curie point, the ferromagnetism disappear.
What is thermally unstable mean?
If a substance is thermally unstable it means it breaks down at high temperature. It cannot withstand high temperature.
Why could it be dangerous to determine if a substance is a base by taste?
Some substances with high pH's are toxic, e.g. bleach.
