Which is an example of a free expansion of a gas? the expansion of a gas due to a chemical reaction among its particles the uncontrolled expansion of a gas into a vacuum the expansion of a gas as it performs work on its container the expansion of a gas as heat is transfered to it at constant pressure

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .

The ability to make things happen is also called a. heat b. force c. matter d. energy
