If an average person jogs he produces `14.5 xx 10^3` cal/min. This is removed by the evaporation of sweat. The amount of sweat evaporated per minute (assuming 1 kg requires `580 xx 10^3` cal for evaporation) is

A

0.25 kg

B

2.25 kg

C

0.05 kg

D

0.20kg

Text Solution

Verified by Experts

The correct Answer is:
A
The amount of sweat evaporated/minute,
`="sweat produced/minute"/"number of calories required for evaporation per kg"`
`="calories produced (heat produced) per minute during jogging"/"latent heat (in cal/kg)"`
`=(14.5xx10^3)/(580xx10^3)=145/580`=0.25 kg

A metal rod AB of length 10x has its one end A in ice at 0^@C , and the other end B in water at 100^@C . If a point P one the rod is maintained at 400^@C , then it is found that equal amounts of water and ice evaporate and melt per unit time. The latent heat of evaporation of water is 540cal//g and latent heat of melting of ice is 80cal//g . If the point P is at a distance of lambdax from the ice end A, find the value lambda . [Neglect any heat loss to the surrounding.]

An electron moving with the speed 5 xx 10^6 m per second is shooted parallel to the electric field of intensity 1 xx 10^3 N/C. Field is responsible for the retardation of motion of electron. Now evaluate the distance travelled by the electron before coming to rest for an instant, (mass of e = 9.1 xx 10^(-31) kg)

A child running a temperature of 101 ^(@) F is given an antipyrin (1.e. a medicine that lowers fever) which causes an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^(@) F in 20 minutes, what is the average rate of extra evaporation caused by the drug. Assume the evaporation mechanism to be the only way by which heat is lost. The mass of the child is 30 kg The specific heat of human body is approximately the same as that of water, and latent heat of evaporation of water at that temperature is about 580 " cal g"^(-1) .

A brass boiler has a base area of 0.15 m^(2) and thickness 1.0 cm. It boils water at the rate of 6.0 kg/min when placed on a gas stove. Estimate the temperature of the part of the flame in contact with the boller. Thermal conductivity of brass = 109 J s^(-1) m^(-1) K^(-1) , Heat of vaporisation of water = 2256 xx 10^(3) J kg^(-1) .

An ice cube of mass 0.1 kg at 0^@C is placed in an isolated container which is at 227^@C . The specific heat s of the container varies with temperature T according to the empirical relation s=A+BT , where A= 100 cal//kg.K and B = 2xx 10^-2 cal//kg.K^2 . If the final temperature of the container is 27^@C , determine the mass of the container. (Latent heat of fusion for water = 8xx 10^4 cal//kg , specific heat of water =10^3 cal//kg.K ).
