The topics of the activities, which use materials commonly found in the home, are: (1) gases can push; (2) additional examples that gases can push; (3) air pushes upward; (4) compressed air changes temperature when it goes through a small opening into a place of lower pressure; (5)...
What is the nature of expandability of gases? When pressure is exerted on gas, it contracts. On the other hand, when pressure is freed, the gas expands. Q4 Explain the nature of diffusibility in gases. The molecules of the gas are in perpetual motion at a very high velocity. There is...
To find the pressure exerted by the box on the ground, we can follow these steps: Step 1: Determine the weight of the boxThe weight of the box can be calculated using the formula:Weight=mass×gravitational forceGiven that the mass of the box is 10 kg and the weight of 1 kg is 10 ...

Step-by-Step Solution:1. Understanding Boiling Point: The boiling point of a liquid is the temperature at which its vapor pressure equals the external pressure surrounding the liquid. At this point, the liquid
Of all the sciences, physics is unique in that it can come to a broad consensus with math alone—very little tactile evidence required. Never has this been the case more than with dark matter. Though it's far more abundant than thematterwe can see and feel, dark matter as we know it...
as straightforward as that. Thermodynamic temperature is a statistic that can only be described meaningfully in the thermodynamic limit (i.e., assumes many particles are present). Since a vacuum is a rarefied gas with a very low particle density, the statement of the thermodynamic limit is ...
and is highlighted in the Things Great and Small features in Conservation of Momentum. See, for example, microscopic description of collisions and momentum or microscopic description of pressure in a gas. This present section is devoted entirely to the submicroscopic explanation of solids and liquids...
