If an avarage person jogs, he produces `14.5xx10^(4) cal//min`. This is removed by the evaporation of sweat. The amount of sweat evaporated per minute (assuming `1 kg` requites `580xx10^(3)` cal for evaporation) is

A

0.25kg

B

2.25kg

C

0.05kg

D

0.20kg

Text Solution

Verified by Experts

The correct Answer is:
A
Amount of sweat evaprated/minute
`("Sweat produced"//"minute")/("Number of calories required for evaporation"//kg)`
`("Amount of heat produced per minute in jogging")/("Latenheat" ("in cal"//kg))`
`(14.5xx10^(3))/(580xx10^(3))=(145)/(580)=0.25kg`

If an average jogs, he produces 14.5xx10^(3) cal/min. This is removed by the evaporation of sweat. The amount of sweat evaporated per minute (assuming 1 kg requires 580xx10^(3) cal for evaporation) is

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.]

A feverish person is running a temperature of 101^@F and is given paracetamol to lower his temperature. Due to medicine, there is an increase in rate of evaporation of sweat from his body. The mass of the person is 50 kg and the specific heat of human body is approximately about 1 cal g^(-1) ""^@C^(-1) . If the fever is brought down to 98^@F in 25 mins, the average rate of extra evaporation caused by the medicine is R in g "min"^(-1) , then the value of 87R/100 is (Latent heat of water at that temperature=580 g/cal)

A child running a temperature of 101^(@)F is given an antipyrine (i.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 min , 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 water at that temperature is about 580 cal//g .

A child running a temperature of 101^F is given and antipyrin (i.e. a madicine that lowers fever) which cause an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^@F in 20 min., what is the averatge rate of extra evaporation caused, by the drug ? Assume the evaporation mechanism to 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 thermally insulated vessel contains 150g of water at 0^(@)C . Then the air from the vessel is pumped out adiabatically. A fraction of water turms into ice and the rest evaporates at 0^(@)C itself. The mass of evaporated water will be closest to : (Latent heat of vaporization of water =2.10xx10^(6)jkg^(-1) and Latent heat of Fusion of water =3.36xx10^(5)jkg^(-1) )
