What is the change of state in a lit candle?
The change of state in a lit candle is from solid (wax) to liquid (molten wax) to gas (vaporized wax) as the heat from the flame melts the wax and turns it into vapor that burns, releasing heat and light.
Is a candle melting a physical change or a chemical change?
The melting of a candle is a physical change because it is a change in state from solid to liquid without altering the chemical composition of the candle.
Is a candle melting chemical or physical?
The melting of a candle is a physical change. It involves a change in state from solid to liquid due to the absorption of heat energy, without any change in the chemical composition of the candle wax.
Is candle wax hardening a physical or chemical change?
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
When alchohol and mercury boil they both change from a liquid to what?
When alcohol and mercury boil, they both change from a liquid to a vapor/gas.
What is the change of state in a lit candle?
The change of state in a lit candle is from solid (wax) to liquid (molten wax) to gas (vaporized wax) as the heat from the flame melts the wax and turns it into vapor that burns, releasing heat and light.
What the of change is a change of state?
The solid wax of the candle melts, and eventually vapourises, then burns and becomes a gas.
What is the change of state in which a gas becomes a liquid?
This change of state is called condensation.
Is a candle melting a physical change or a chemical change?
The melting of a candle is a physical change because it is a change in state from solid to liquid without altering the chemical composition of the candle.
Is a candle melting chemical or physical?
The melting of a candle is a physical change. It involves a change in state from solid to liquid due to the absorption of heat energy, without any change in the chemical composition of the candle wax.
When a liquid becomes a solid the change of state is known as?
melting
What is the change of state when solid aluminium becomes liquid?
The change of state when solid aluminum becomes liquid is called melting. This occurs when the temperature of the solid aluminum is raised above its melting point, causing the particles to gain enough energy to break free from their fixed positions and transition into a liquid state.
What kinds of energy are needed in this investigation to change the state of matter of the candle?
The energy needed to change the state of matter of a candle is primarily in the form of heat energy. When the candle is lit, the heat energy from the flame melts the candle wax, causing it to change from a solid to a liquid state. Further heating vaporizes the liquid wax, transforming it into gaseous wax molecules that combine with oxygen to produce light and heat energy.
Change in which a solid becomes a liquid?
The change of state is Melting. Solid to liquid is melting. E.g. ice to water
Is candle wax hardening a physical or chemical change?
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
When alchohol and mercury boil they both change from a liquid to what?
When alcohol and mercury boil, they both change from a liquid to a vapor/gas.
How does the state of matter of wax in a candle change when the candle is lit an need an answer?
When a candle is lit, the wax melts into a liquid state due to the heat from the flame. The liquid wax is then drawn up the wick through capillary action and vaporizes into a gas, which is what burns to produce the flame.
