Plz eplain me the anomalous expansion of water or HOPE'S experiment plzzzzzzzzz
why r cloudy nights warmer than the calm and clear nights?
Give reason: Small holes are provided at the bottom of the chimney in an oil lamp
why a vessel containing liquid always heated from below rather than from the sides
why are cement / concrete floors made into smaller section with metal / glass strips in between ?
why in a clinical thermometer the bulb is not quite full of mercury at room?
describe the principle and working of Davy's safety lamp??
is humidity inversely proportional 2 heat?
why is boiler covered with a layer of asbestos
how does a digital thermometer work ??????????
How much will a bar of aluminium, 100cm long, expand when heated from 20 C to 100 C ? Coefficient of linear expansion of aluminium is 0.000025 C
give reason why it is cool in shade when it is hot outside.
Due to the anomalous expansion of water the capillaties of plants burst when the temperature falls below 4 degrees Celsius.This is because the water inside the capillaries expands,exerts pressure on the capillaries and so they burst.To prevent plants from dying in this way,farmers fill their fields with water.How does this prevents the capillaries from bursting??????
define the coefficients of real and apparent expansion of a liquid.
how do you explain the process of conduction in solids?
