Atomic theory, which describes the atoms that make up matter, has been explored for centuries. Scientists in ancient Greece first proposed that matter was made of units called atoms. For many years, scientists thought atoms were solid and could not be divided. Then, in the nineteenth century, scientists began to discover the particles that make up atoms. Modern techniques have allowed scientists to split atoms into increasingly smaller particles. Which of the following statements about theories is supported by the history of the atomic theory? A. If new evidence contradicts earlier theories, it is a result of an experimental error.
B. Experiments with modern equipment cannot be used to support earlier theories.
C. A theory is discarded when new evidence contradicts a part of the theory.
D. Theories can change in response to new evidence.

The goal of this experiment was to answer the question "what is the effect of a gas' temperature on its volume? " you formulated the hypothesis below. hypothesis: if a fixed amount of gas is heated, then the volume will increase because the heat will cause the molecules of gas to move faster and further apart. to test this hypothesis, you changed the of the gas between 0 and 100°c (273 and 373 k) and calculated the resulting of the gas.
