A 74.2 g sample of an unknown substance experiences a temperature change of 8.63 °C while absorbing 736.8 joules of heat. What is the specific heat capacity of this substance? Equation: q=mCΔT

Cwater = 4.18 J/goC

Cwater = 1.00 cal/goC

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
