When the pressure at the bottom of a submerged object is less than the pressure at the top of the submerged object a buoyant force is produced?
Answer:c is the answer every 2 hours A is just plain no B four hours is too long and D is a no you need to rest
Explanation:
Answer:
C
Explanation:
Answer:
2
Explanation:
The object's density is calculated by dividing its mass (10 grams) by its volume (5 cubic centimeters), yielding a density of 2 g/cm³.
The density of an object is calculated by dividing its mass by its volume. For the object in question, its mass is 10 grams and its volume is 5 cubic centimeters. Therefore, you would calculate density as follows: Density = Mass / Volume. Plug in the values and you get: Density = 10 grams / 5 cubic centimeters. This equals 2 g/cm³. Hence, the density of the object is 2 grams per cubic centimeter.

B. water
C. smoke
D. ice
The gaseous state of a liquid is called as vapor under normal conditions of temperature and pressure.
Answer: Option A
Explanation:
Vapor is a form of substance floating in air where increasing or decreasing the temperature and pressure changes the state of the substance into gas or liquid.
For example : consider water where heating it to the boiling point makes it as water vapor and reducing its temperature makes it as ice.
Under normal conditions of temperature and pressure, the gaseous state of a liquid is called vapor. The correct answer is A.
When a liquid is heated or its pressure is reduced, the kinetic energy of its molecules increases, causing them to gain enough energy to overcome intermolecular forces and transition into the gaseous state. This gaseous form of a substance, while retaining the same chemical composition as the liquid, is called vapor.
Let's examine why the other options are not true:
B. Water: Water specifically refers to the liquid state of H2O molecules. While water can exist as a liquid, solid (ice), or gas (water vapor), under normal conditions, the gaseous state of a liquid is referred to as vapor rather than water.
C. Smoke: Smoke is not the gaseous state of a liquid. It typically consists of tiny solid particles or liquid droplets suspended in the air, resulting from the incomplete combustion of organic matter. Smoke is not directly related to the gaseous state of a liquid substance.
D. Ice: Ice refers to the solid state of water. It is the result of the cooling and freezing of liquid water molecules. Ice is not related to the gaseous state of a liquid substance.
Therefore, under normal conditions of temperature and pressure, the gaseous state of a liquid is called vapor. While water refers to the liquid state, smoke is not directly related, and ice represents the solid state of a liquid substance.
