Energy
all things living needs Energy and life :)
Examples : sublimation, deposition, boiling, melting, freezing.
The state of matter remain unchanged.
no physical change does not change matter
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 of state.
state of matter
The state of matter remain unchanged.
a change in size, shape or the state of matter is a physical change. True for A+.
It can.
Yes, a net force is needed to change the speed or direction of moving matter. Newton's first law of motion states that an object will remain in its state of motion unless acted upon by an external force. When a net force is applied, it can accelerate the object, decelerate it, or change its direction.
Because melting is a change of state: from solid to liquid.
