It's important to understand your three states of matter because it helps you understand your surrounding and also what things change shape and why and what things stay the same and why.
Answer:
A medida que aumenta la temperatura de un líquido, la solubilidad de los gases en ese líquido disminuye. Podemos usar la Segunda Ley de la Termodinámica para explicar por qué. Calentar una solución de un gas permite que las partículas de gas se muevan más libremente entre la solución y la fase gaseosa. La Segunda Ley predice que cambiarán al estado más desordenado, más altamente disperso y, por lo tanto, más probablemente gaseoso.
Explanation:
Hello!
So, we are given a ball with a density of 1100 kg/m³, and two liquids: water (1000 kg/m³) and honey (1400 kg/m³). Our goal is to determine if the ball will sink or float in the given liquids.
Let's take two common substances: water and ice. Water has a density of 1000 kg/m³ and ice has a density of about 917 kg/m³. You would notice that the ice is always floating when you put ice and water together. This would occur if you have other substances.
Here's what you should know:
- If the density of an object is greater than the liquid it is in, then that object will sink.
- If the density of an object is less than the liquid it is in, then that object will float.
Since the ball has a density of 1100 kg/m³, and water's density is 1000 kg/m³, then the ball will sink. If the ball is placed in honey, then it will float because the density of honey (1400 kg/m³) is greater than the ball's density.
Therefore, objects with a greater density than the surrounding liquid sink, while objects with a smaller density than the surrounding liquid float, which is the fourth choice.
Answer:
B. Smaller Particles
Explanation:
We know that the rate of reaction increases with increase in the surface area of reactants.
The reacting particles in the log of wood are embedded inside the wood making only very minimal amount of particles available for reaction. This ultimately slows down the rate of combustion.
However, in saw dust, there is a greater availability of surface area of reactants hence the sawdust burns faster than logs.
