(a) If the lizard has a specific heat of 4.2 J/(g x C), what is rate of increase of the lizard’s temperature?

(b) Assuming that there is no heat loss by the lizard (to simplify), how long must the lizard lie in the sunlight in order to raise its temperature by 5.0 C?

**bobpursley**, Saturday, January 19, 2013 at 9:10pmI think you might be answer grazing.

HeatLizardabsorbs=.5 heat sun

mass*c*deltaTemp=.5*Intensity*area*time

deltaTemp/time= you do the math.

then for part b, calculate time for a deltaTemp of 5.

deltaTEmp/time known in part a.

part a= 5C/time calculate time
