effect temperature

The effect of temperature has already been discussed earlier under limitations of ohm's law. In general for metallic conductors higher the temperature larger is the resistanc..

A chemical equilibrium involves two opposing reactions. If one of them is exothermic, the other must be endothermic. If a system at equilibrium is subjected to change in temperature, the equilibrium adjusts itself to counteract the effect of the applied change. Thus, if the ..

Generally, the rates of chemical reactions increase with increase in temperature. It is a common observation that perishable foods like milk, cooked vegetables decay more quickly in summers than in winter. Consider the chemical reaction: At 273 K, the reaction is extremely slow and ..

Where T and T 0 are the temperatures on the Kelvin scale corresponding to t o C and 0 o c. Thus, the velocity of sound in a gas varies directly as the square root of the absolute temperature..

The value of Kw varies with the change in temperature. The values of [H 3 O + ] and [OH - ] are always equal to each other at all temperatures but the values of K w are different at different temperatures. The value of K w increases with the rise in temperat..

When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperature at which it melts under one atmospheric pressure. Increase ..

At ordinary temperatures and pressures, chlorides, bromides and iodides of lithium, sodium and rubidium and some halides of silver possess the NaCl structure with 6:6 co-ordination. On application of high pressure they transform to the CsCl structure with 8:8 co-ordination. On the other ..

According to the Le Chatelier's principle, this will make the reaction move in a direction which absorbs heat i.e., the endothermic process will be favoured. As vaporization (liquid g vapours) is an endothermic process, a rise in temperature will favour the process of vaporization i.e. m..
