2nd answer
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.
3rd answer
Those substances which change their colors in acid and base are called acid-base indicators for example litmus solution,methyl red, methyl orange and beetroot etc.
4th answer
The uniform motion is identical to the actual speed of the object. The non-uniform motion is different from the actual speed of the object. Uniform motion covers equal distance at an equal time interval. Non-uniform motion covers unequal distance at equal time interval.
