Saudi Prince Gave Kristen Stewart 500k USD for 15 Minutes

A bulb of 100 watt is switched on in a room of dimensions 5xx4xx3 m^(3) . What will be the increases in temperature of room after 15 minute, if specific heat of iar at room temperature and 1 atm is 0.71 J g^(-1) K^(-1) and heat capacity of four walls and the roof is 50xx10^(3) JK^(-1) ? (Density of air 1.22xx10^(-6) kg mL^(-1) )

The 2.0 Omega resistor show in figure is dipped into a calorimeter containing water. The heat capacity of the calorimeter together with water is 2000 J K^(-1) . (a) If the circuit is active for 15 minutes, what would be the rise in the temperature of the water? (b) Suppose the 6.0 Omega resistor gets burnt. What would be the rise in the temperature of the water in the next 15 minutes? (Figure)

The half-life of a substance in a first-order reaction is 100 minutes at 323.2 K and 15 minutes at 353.2 K. Calculate the temperature coefficient of the rate constant of this reaction.

Rohan covers 2/3 rd of a certain distance in 2 hours 30 minutes at the rate of x kmph. He covers the remaining distance at the rate of (x + 2) kmph in 50 minutes. What is the total distance? 21 k m b. 18 k m c. 16 k m d. 15 k m

The rate of the reaction is proportional to the concentration of the reactant. Hydrogenation of ethene results in the formation of ethane. The rate constant, k for the reaction was found to be 2.5xx10^(-15)s^(-1) . The concentration of the reactant reduces to one-third of the initial concentration in 5 minutes. Q. The rate constant of the reaction after 5 minutes is:
