Question

increase and decrease

(a) Define specific heat. Specific heat is defined as the quantity of heat required to raise the temperature of 1 gram of a substance kelvin (b) Explain what is meant by saying the specific heat of water is 4.18 1/g-K. gram(s) of water must absorb 4.18 J/g-K of heat to raise its temperature (c) Assuming the specific heat of a substance is constant, what will happen to the quantity of heat transferred if the following occur. (I) We wish to heat more than 1 g of water 1 K. The quantity of heat transferred will Seld-! (ii) We wish to heat a 1 g mass of water to 2 K rathethan 1 K. The quantity of heat transferred will-Select-? Specific heat is defined by the equation where c. is the specific heat, g is the quantity of heat transferred, m is the mass of the substance in grams, and ?? ls the temperature change.

Assuming no heat is lost to the surroundings, calculate the final temperature of the two sheets of metal. e C Supporting Materials

Explanation / Answer

part A) the temperature by 1 kelvin

part B) 1 g of water must absorb ...................to raise its temperature by 1 kelvin

part C) heat transferred is given by eqn Q = mcDeltaT

so mass increases the heat increases

2) as also if we want to raise temperature by 2 not 1 then more heat has to be supplied..

for last question C data for both nickel and lead must be known...

(MCdeltaT)nickel = (MCdeltaT)lead

delta T for nickel would be T - 16

delta T for lead = 65 - T and T has been taken as final temperaute of both the block..
