Yes, the refractive index of a liquid often is different at different temperatures (usually negative; e.g. It goes down as temperature goes up), although typically the effect is very nominal. However, that is not to say that there is a constant relationship between Ref index & temperature. Refractive index is proportional to the square roots of electrical permittivity and magnetic permeability. These factors may change with temperature, but not linearly, and therefore RI does not have a simple relationship with temperature.
Glasses of various types have refractive indices ranging from 1,4 to over 2,0
Usually a convex lens made up a material with higher refractive index would act as a converging device when kept in a medium having lower refractive index such as air. But when it is kept in a liquid as said with higher refractive index then convex lens would become as a concave lens. Now it would diverge the rays entering through it right from the liquid with higher refractive index.
The (very high) refractive index of diamond is 2.4 at room temperature.(From Wikipedia: "Refractive index also describes the quantity that light is bent as it passes through a single substance."
Refractive Index: 1.4465
it changes its refractive index.

what are the factors affect for refractive index
determine the refractive index of a transparent liqiud
Impurities can cause a significant change in the reflective index of a liquid. Impurities totally affect the results of the experiment. It changes the reflective index and affect the concentration of the solution.
Changing the pH the chemical composition is changed; as a consequence the the refractive index is influenced.

The refractive index is a physical property of the medium that depends on the wavelength of the light, and the temperature. The temperature needs to be specified, and is usually 20 or 25 degree Celsius. The refractive index decreases with increasing temperature, and for most organic compounds one can correct for the temperature.
Refractive Index: 1.4465
Refractive index of vacuum is 1.
