Related to this Question What term describes the process when a solid phase changes directly to the gas phase? Phase change from solid to gas is known as ___. The process by which a substance changes from its liquid phase to its gas phase is known as? Which...
A. Sublimation B. Evaporation C. Condensation D. Distillation 相关知识点: 试题来源: 解析 A。固体直接变为气体的过程称为升华(Sublimation)。“Evaporation”是蒸发,指液体变为气体;“Condensation”是冷凝,气体变为液体;“Distillation”是蒸馏。本题描述的是固体到气体,所以是升华,选 A。反馈...

Tell whether each item is a solid, liquid, or gas. 3rd through 6th Grades States of Matter Anchor Chart This printout defines the three states of matter: gas, liquid, and solid. Simple graphics and informative text describe how each form moves and changes (or doesn't change) shape. ...
Figure 6.1.5 also shows the changes of gas temperature, pressure, energy, and the horsepower produced in the different sections of the gas turbine. Note that the power produced in a gas turbine is typically three times the output power. This is because the air compressor typically requires ...
The transport options preferred by governments and companies not only must take the economic risks into account but also consider the negative effects of possible terrorist activity, political changes, and trade embargos over long periods of time. Thomas and Dawe (2003) covered many of the essential...
To determine the position at which hydrogen molecules are absorbed into the chemical adsorption system, energy scans have been performed using single-point energy changes as a function of the radial distance of the H2 molecule from the center of the H2 adsorbent system to the outer surface95,96...
When a solid is converted directly to a gas, the change of state is called ___. Phase transition Generally a solid first converts into a liquid and then into a gas. But under certain conditions of temperature and pressure, certain compounds turn directly to ...
