What else can I help you with?
True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
Is Phase of any substance is dependent upon temperature and pressure?
true
Is The phase of any substance is dependent upon temperature and pressure true or false?
do you have homeschool that your asking this because i do and im looking for the same answer
A material showing perfect conductivity and Meissner effect below a critical temperature Is this true or false?
Superconductor
Is Reese waters dating?
Yes. It is true to say that Reese Waters is dating.
True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
Do cold temperatures have a vasoconstricting effect on blood vessels?
Yes. Increased body temperature that is associated with a cold can cause the vasodilation effect and heart rate increases
Why electrocaloric effect observed in ferroelectric polymers only?
Its not true that electrocaloric effect (ECE) is observed only in ferroelectric polymers. ECE can be found in any typical dielectric material. If polarization switches from one direction to the other upon application or withdrawl of electric filed, the temperature of the material changes. It happens both in organic as well as inorganic materials. It is found that the EC coefficent is high near ferroelectric phase transition temperature.
When heat is added to a liquid at the boiling temperature it converts the liquid into a gas at the same temperature because?
The additional heat, called "enthalpy" completes the phase change, by changing the arrangement of the molecules in the existing environment, not the temperature. The energy must be removed from a gas to cause condensation into liquid, and from a liquid to cause solidification (freezing). Conversely, it is added when changing a solid to a liquid or a liquid to a gas. At a certain temperature (critical temperature), the process happens spontaneously because the phase boundary disappears.
Was mercantilism an early phase of capitalism?
That is true, mercantilism was an early phase of capitalism.
True or false pirates once controlled the waters around parts of Madagascar?
true
Which types of compounds can exist as solids liquids or gases?
Covalent.Every compound can exist as a solid, liquid, or gas, given the right temperature and pressure. This is also true of every element, with the single exception of helium, which has no solid phase, no matter how cold it is. Helium is unique.
