The correct answer is false.
Explanation:
in it I mass=150g,initial temp 1=95,mass2=500g,temp2=?,final temperature=27.2 C1=0.444C2=4.18
using formula
m1c1(final temp-initial temp1) =m2c2(temp2-final temp)
150x0.444(27.2-95)=500x4.18(?-27.2)
66(-67.8)=2000(?-27.5)
-4474.8=2000?-55000
collect like terms
-4474.8+55000=2000?
50525=2000?
divide both sides by 2000
2000?/2000=50525/2000
initial temperature =25.26 degree Celsius
Specific heat is the quantity of heat required to change the temperature of 1 gram of a substance by 1 degree Celsius. It is the amount per unit mass that is required to raise the temperature by one degree Celsius. Every substance has its own specific heat and each has its own distinct value. The units of specific heat are joules per gram-degree Celsius (J/f C) and sometimes J/Kg K may also be used.
