 \[{{6.5}^{\circ }}C\]then the mass of steam condensed is
A. 17.5 g
B. 11.7 g
C. 15.7 g
D. 18.2 g

Answer 1

Hint: A calorimeter is an object utilized for calorimetry, or the way toward estimating the heat of compound responses or physical changes just as heat limit.

Complete answer:
Differential filtering calorimeters, isothermal small-scale calorimeters, titration calorimetry and quickened rate calorimeters are among the most well-known sorts
The correct answer is B.
Let x be the mass of steam condensed. The heat obtained calorimeter with water is equal the heat from condensing x kg of steam and the heat from cooling x kg of water to the final temperature of calorimeter with water
\[x.L+x.c.({{T}_{3}}-{{T}_{2}})=(m+{{m}_{C}}).c.({{T}_{2}}-{{T}_{1}})\]
\[x=\dfrac{(m+{{m}_{c}}).c.({{T}_{2}}-{{T}_{1}})}{L.c({{T}_{3}}-{{T}_{2}})}\]
\[x=\dfrac{({{1.1.10}^{3}}g+20g).1\dfrac{cal}{g.\deg ree}.6.5\deg ree}{540\dfrac{cal}{g}+1\dfrac{cal}{g.\deg ree}.(373K-294.5K)}\]
\[=12g\simeq 11.7\]g
A simple calorimeter just consists of a thermometer joined to a metal compartment brimming with water suspended over a burning chamber. It is one of the estimation gadgets utilized in the investigation of thermodynamics, science, and natural chemistry.
To discover the enthalpy, change per mole of a substance out of a response between two substances A and B, the substances are independently added to a calorimeter and the initial and final temperatures (before the response has begun and after it has completed) are noted.
Increasing the temperature change by the mass and specific heat limits of the substances gives an incentive for the energy radiated or assimilated during the response. Isolating the energy change by what number of moles of A were available gives its enthalpy change of response.
\[q={{C}_{v}}({{T}_{f}}-{{T}_{i}})\]
Where q is the measure of heat as indicated by the adjustment in temperature estimated in joules and Cv is the heat limit of the calorimeter which is a value related with every individual device in units of energy per temperature (Joules/Kelvin).

Note: The body at higher temperature discharges heat while the body at lower temperature assimilates heat. The rule of calorimetry demonstrates the law of protection energy, for example the absolute heat lost by the hot body is equivalent to the complete heat picked up by the virus body.
