Question

Transcribed Image Text:The following information is given for magnesium at 1 atm:
Th = 1090. 00 C
= 649.00 C
Im
= 5.24x10³J/g
A Hyap
= 368.3 J/g
A HFUS =
Specific heat of liquid= 1.017J/gC
Specific heat of solid= 1.339J/gC
A 33.00 g sample of solid magnesium is initially at 624.00°C. If 1.473x10^4J of heat
are added to the sample at constant pressure (P= 1 atm), which of the following
is/are true?
The sample is at a temperature of 649C
The sample is a solid in equilibrium with liquid
The sample is a solid
The sample is at a temperature greater than 649C
The sample is a liquid

Transcribed Image Text:In the laboratory a student finds that it takes 67.2 Joules to increase the temperature
of 10.1 grams of solid nickel from 20.2 to 36.0 degrees Celsius.
The specific heat of nickel calculated from her data is:
O 0.421J/gC
O-0.118J/gC
O-0.421J/gC
O0.118J/gC
