In what there is no change of temperature?
Answer. Answer: When solid melts, the temperature remains the same, this is because the absorbed heat is utilized in breaking the forces of attraction between the particles and hence solid changes to a liquid state without changing in temperature.
What are the conditions when there is no change in the temperature?
The conditions when there is no change in the temperature of a substance even when it is being heated is latent heat. Explanation: When you add heat energy to a substance and the temperature rises, the average kinetic energy of the particles is increasing.
Why does heat change happen?
The temperature changes are the result of the added energy causing the particles of water to move more vigorously. Either the particles of solid vibrate more vigorously about their fixed positions or the particles of liquid and gas move about their container more rapidly.
When water is heated with rise of temperature its consumes?
When ice is heated, the kinetic energy of water molecules rises. Kinetic energy rises because water molecules absorb energy and begin to move more. From the graph, regions of rising kinetic energy are: A, C, and E. However, while the ice is being heated, its temperature stops rising at 0 °C.
What changes can an object undergoes on getting heated?
When a solid is heated the particles gain energy and start to vibrate faster and faster. Initially the structure is gradually weakened which has the effect of expanding the solid. Further heating provides more energy until the particles start to break free of the structure.
What happens when heat is taken away from matter?
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
Why does a solid change to liquid when heat is added a the spacing between particles decreases B particles lose energy C the spacing between particles increases D the temperature decreases?
Solids is the state of matter in which the atoms of the matter are closely packed by the strong forces. When solid is converted to liquid, these force has to be broken in order for the conversion to take place. This energy overcome the forces of attraction and the spacing of the atoms decreases and turns into liquid.
