In solids, heat is move from conduction. We will study conduction of heat energy by a solid bar in the following section.
Given a solid bar of thickness and area of cross-section A. The left side of the bar is get at a temperature ΦA and right side at ΦB.
Let us consider that ΦA > ΦB.
Heat moves from high to low temperature i.e., from left side to right side, as given in fig.
After some time, temperature of each section becomes constant with time. This is called as steady state.
Two elements A and B form compounds having molecular formulae AB 2 and AB 4 . dissolved in 2O g of benzene, 1 g of AB2 lower the freezing point by 2.3 K, whereas 1 g of AB4 lowers
The physical value which does not depend on any other physical quantity is known as a fundamental physical quantity like length; mass and time are known as fundamental units.
Galvanometer: 1. An electromechanical instrument, which is used to detect the presence of current in a circuit is known as galvanometer. 2. The major parts of a galvanomete
Can the whole charge of a body is transfer to another body
All the given four Laws may be written in one relation, PV = nRT =m/n RT This formula is known as deal gas equation. Where m = mass of the gas M = molecular mass of t

A 12 volt battery is associated across a series combination of two capacitors C1 and C2. The capacitance of C2 is double that of C1.
Interconnection of cells: Cells may be connected in series, parallel or any combination of the two in order to form a battery. When cells are connected to form a battery they s
