Question

What are examples of physical and chemical change through the application of heat in the spaces provided?

Answer 1

Answer:

physical change through heat like melting of ice cubes and changing into water this leads due to the rise of temprature and in chemical change burning of paper.

Answer 2

Some examples of physical change through heat-

• water vaporization or turning of liquid water into steam
• melting of wax due to heat
• melting of ice into the water also involves heat
• liquefaction of gases under influence of temperature

Some examples of chemical changes brought by heat-

• Burning of fossil fuels such as petrol or diesel and getting converted into carbon dioxide
• Burning of paper and getting reduced to ashes
• cooking food is also a chemical change

• Heating graphite under heat and pressure and converting into diamond

Any reaction that brings changes in the physical form of an object is called a physical change whereas any reaction that changes the chemical nature of substance is called as chemical change.
