Why does the temperature remains constant when ice changes into water |
|
Answer» The heat energy (latent heat) supplied to ice during the change of state at its melting point is all used up in overcoming the force of attraction between the particles without increasing its kinetic energy.Since the latent heat supplied to ice during change of state at its melting point doesn\'t increase the kinetic energy.Therefore,there is no rise in temperature.Thus,the temperature remains constant when ice changes into water. Becoz the heat given to the ice is latent heat. In latent heat , form of water is changes but temperature remains constant. Bcoz the tempeature goes to break the interparticle forces. Hence it doesn\'t increase the kinetic energy is not increased that results that the temperature remains constant. The ice changes into waterbecause ice at room temp.starts melting and changes into water Because temperature are change it state of matter |

State difference between average speed and average velocity |
| Answer» Average speed means the total distance travelled by a body in unit time. It is a scalar quantity because it has magnitude only it has no direction. Average velocity is the distance travelled by a body per unit time in a specified direction . It is vector quantity because it has magnitude as well as direction. . | |

What is velocity????? |
|
Answer» The rate of change of displacement ...And it is a vector quantity The rate of change of displacement. The rate of charge of displacement And velocity is a VECTOR quantity (has both magnitude & direction) ; SI unit- meter/sec = m/s. It is displacement covered by an object . It\'s expression is: velocity = displacement over time . It is a scaler quantity. DEFINATION Velocity is displacement per unit time . Or. Velocity is rate of change of displacement. Formula v = s ÷ t , wherev = velocity, s = displacement, t = time taken . |

What would happen if the cell membrane rupture |
|
Answer» If the Plasma membrane ruptures or breakdown then the cell will not be able to exchange material from its surrounding by diffusion or osmosis. Thereafter the protoplasmic material will be disappeared and the cell will die.
