| Until early in the present century scientists made use of a law of conservation of matter and a law of conservation of energy. |
|
| Or do those calculations of yours freely infringe the law of conservation of energy but have scruples about the conservation of mass? |
|
| Bernoulli's principle is basically a statement of the law of conservation of energy written for the movement of a fluid such as air. |
|
| Analyse quantitatively the relationships among mass, height, speed, and heat energy using the law of conservation of energy. |
|
| Of course this was not a comfortable place to be, but it was slightly less uncomfortable than violating the law of conservation of energy. |
|
| The law of conservation of energy is applied not only to nature as a whole but to closed or isolated systems within nature as well. |
|
| This sequence of events does not violate the law of conservation of energy because energy is returned quickly enough to create an overall equilibrium. |
|
| This led to the law of conservation of energy, which led to the development of the first law of thermodynamics. |
|
| Einstein and Max Planck demonstrated once again that energy could neither be created nor lost and that it left one system only to join another — the famous law of conservation of energy. |
|
| The first law of thermodynamics, or the law of conservation of energy, states that the heat and work produced must equal the energy released by the chemical reactions. |
|
| This assumption violates the first law of thermodynamics, also called the law of conservation of energy, which states that the total energy of a system is always constant. |
|
| The law of conservation of energy applies. |
|
| As Devin Powell reports in this issue, such superluminal speeds not only defy Einstein's special relativity, but they also contradict the law of conservation of energy. |
