The temperature range of box type solar cooker kept in the sun for 2-3 hours will be……..

Draw a labelled diagtram of a box type solar cooker,also give its working and advantages

A motor vehicle radiator was filled with 8L of water to which 2 L of methyl alcohol (density 0.8g/mL) were added. What is the lowest temperature at which the vehicle can be parked outdoors without a danger that water in the radiator will freeze? K_f of water = 1.86Km^-1 .

Three closed rigid vessels, A, B and C, which initially contain three different gases at different temperatures are connected by tube of negligible volume, without any energy transfer with surroundings. The vessel A contain 2 mole Ne gas, at 300 K, vessel 'B' contain 2 mole SO_(2) gas at 400 K and vessel 'C' contain 3 mole CO_(2) gas at temperature 500 K. What is the final pressure (in atm) attained by gases when all valves of connecting three vessels are opened and additional 15.6 kcal hear supplied to vessels through valve. The volume of A, B and C vessel is 2, 2 and 3 litre respectively Given :R =2 calorie/mol-K, C_(v)(Ne)=3//2R,C_(v)(CO)=5//2R and C_(v)(SO_(2))=3R

Vapour pessure of a liquid or a solution is the pressure exerted by the vapour in equilibrium with the liquid or solution at a particular temperature. It depends upon the nature of the liquid and temperature. It depends upon the nature of the liquid and temperature. According to Raoult's law in a solution, the vapour pressure of a component at a given temperature is equal to the mole fraction of that component in solution multiplied by the vapour pressure of that component in hte pue state. this solution in which each component obeys Raoult's law are called ideal solutions. there are two types of non ideal solutions, showing positive deviations and negative deviations from ideal behaviour. If liquid A and B form ideal solution, then

Two towers on top of two hills are 40 km apart. The line joining them passes 50 m above a hill halfway between the towers. What is the longest wavelength of radio waves, which can be sent between the towers without appreciable diffraction effects?

The Sun is a hot plasma (ionized matter) with its inner core at a temperature exceeding 107 K, and its outer surface at a temperature of about 6000 K. At these high temperatures, no substance remains in a solid or liquid phase. In what range do you expect the mass density of the Sun to be, in the range of densities of solids and liquids or gases ? Check if your guess is correct from the following data : mass of the Sun = 2.0 xx 10^30 kg , radius of the Sun = 7.0 xx 10^8 m .
