what is the specific heat of ethyl alcohol if 129 J of heat is required to raise the temperature of 15.0g of ethyl alchohol from 22.7 degree celsius to 26.20 degree celsius? ​

The specific heat of ethyl alcohol : c = 2.457 J/ g ° C  

Further explanation  

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Given

Q = 129 J

m = 15 g

∆T = 26.2 - 22.7 = 3.5

Required

the specific heat

Solution

Input the value :

c = Q / m.∆T  

c = 129 J / (15 g x 3.5 °C)

c = 2.457 J/ g ° C
