How do you appreciate the role of the higher specific heat of water in stabilizing atmospheric temperature during winter and summer seasons?

How can you appreciate the technology of making ships those float on water using the material which sink in water ? (AS_(6))

The specific heat of water is 4180 J / kg°C . How much the heat capacity of 2 kg water ?

Explain why the aquatic species are more conmfortable in cold water during winter season rather than warm water during the summer.

Explain how do you determine the temperature of hot water using laboratory thermometer?

How do you appreciate efforts of a musician to produce melodious sound using a musical instrument by simultaneously controlling frequency and amplitude of the sounds produced by it. (AS_6)

An immersion heater rated 1000 W, 220 V is used to heat 0.01 m^3 of water. Assuming that the power is supplied at 220 V and 60% of the power supplied is used to heat the water, how long will it take to increase the temperature of the water from 15^@ C to 40^@ C ?

A plate of area 10 cm^2 is to be electroplated with copper (density 9000 kg m^(-3) to a thickness of 10 micrometres on both sides, using a cell of 12 V . Calculate the energy spend by the cell in the process of deposition. If this energy is used to heat 100 g of water, calculate the rise in the temperature of the water. ECE of copper = 3 xx 10^(-7) kg C^(-1) and specific heat capacity of water = 4200 J kg^(-1) K^(-1) .

How will you identify the male frog during breeding season.

Eiffel tower is made up of iron and its height is roughly 300 m. During winter season (January) in France the temperature is 2^(@) C and in hot summer its average temperature 25^(@) C. Calculate the change in height of Eiffel tower between summer and winter. The linear thermal expansion coefficient for iron alpha = 10xx10^(-6)" per "^(@)C
