An 8.00 X 102-g block of lead is heated in boiling water, 100.0°C, until the block's temperature is the
same as the water's. The lead is then removed from
the boiling water and dropped into 2.50 X 10² g of
cool water at 12.2°C. After a short time, the temper-
ature of both lead and water is 20.0°C.
a. How much heat is gained by the cool water?
b. On the basis of these measurements, what is the
specific heat of lead?

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
