Explanation:
Googled it
Answer:
(a) decrease
Explanation:
Viscosity is the resistance which occur to flow of the fluid.
More the inter molecular forces between particles of the liquid, more the viscosity of liquid.
<u>Effect of temperature on viscosity:-</u>
Viscosity decreases with the increase in the temperature as forces among the particles decrease on increasing temperature. The kinetic energy of the particles of the liquid increases causing to move in more random motions and thus weaker inter molecular forces and this offer less resistance to the flow.
<u>Hence, viscosity of the liquids decrease with the increasing temperature.</u>
For the answer tot the question above, it is Thermal energy is the portion of internal energy that can be transferred from one substance to another. It is the energy that comes from heat. This is generated by the movement of the particles in an object.
Thermal energy is the energy and object or system has due to the movement of particles within. This results in the object or system having an internal <span>temperature that can be measured with a thermometer.</span>
