What else can I help you with?
Can powder melt?
Yes, powders can melt if their melting point is reached. Melting occurs when a solid substance is heated to a temperature at which its particles can move freely, changing from a solid to a liquid state.
The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first is?
Sublimation is the phase change in which a substance changes from a solid to a gas or vapor without first becoming a liquid. This process occurs when the pressure and temperature conditions allow the solid to transition directly into a gas.
What would increase a temperature of a substance?
An increase in energy input, such as heat transfer from a heat source or mechanical work, would increase the temperature of a substance. This causes the particles in the substance to move faster, leading to an increase in kinetic energy and temperature.
What kind of change happens when the composition of a substance does not change?
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
What determines heat?
Heat is determined by the amount of thermal energy in a substance or system. It is influenced by factors such as the temperature of the substance, its mass, and its specific heat capacity. Heat transfer occurs from regions of higher temperature to lower temperature, following the principles of thermodynamics.
What is meant by the term condensing?
"Condensing" typically refers to the process of changing a substance from its gaseous state to its liquid state by removing heat. This transition usually occurs when the substance reaches a certain temperature known as its "condensation point."
What happens to the temperature when a eclipses occurs?
you die
What happens when rust occurs?
temperature increases.
What is boil in science?
Every liquid has a temperature and pressure at which the substance gives off vapor internally. The temperature and pressure at which this occurs is called the boiling point. The term "boil" means what happens at these points.
At what temperature does oxygen burn?
Oxygen itself does not burn, but it supports combustion. Combustion occurs when a substance reacts with oxygen and releases heat. The temperature at which this reaction occurs varies depending on the substance.
Can powder melt?
Yes, powders can melt if their melting point is reached. Melting occurs when a solid substance is heated to a temperature at which its particles can move freely, changing from a solid to a liquid state.
What is heat transfer that does not cause a temperature change?
Heat transfer that does not cause a temperature change is called latent heat transfer. This occurs when heat is absorbed or released during a change in state (solid to liquid, liquid to gas) without changing the temperature of the substance.
What happens to the mass when a substance when rusting happens?
When rusting occurs the mass of the substance increases since the rusting material reacts with the oxygen in air
What is the process of a substance changing from a solid to a vapor without through the liquid phase is called?
The solid->gas transition is called sublimation; the gas->solid transition is called deposition. The reason this happens is, essentially, "because that's how things are". It all depends on where on the phase diagram the material happens to be.
What happens to the characteristic properties of a substance when a physical change occurs?
i dont know you tell me
What is meant by the word condenses?
In the context of science or physics, condenses refers to the process of a substance changing from a gaseous state to a liquid state by releasing heat. This typically occurs when the temperature of the gas cools down to its dew point.
The phase change in which a substance change from a solid to a gas or vapor without changing to a liquid first is?
Sublimation is the phase change in which a substance changes from a solid directly to a gas or vapor without passing through the liquid phase. This process occurs when the substance's vapor pressure exceeds that of its solid form at a particular temperature.
