A metal rod and a metal ball more submerged in H2O

In summary, the conversation discusses the behavior of metals when submerged in H2O. It explains that a metal rod has a larger surface area and displacement than a metal ball due to its shape. The density of a metal determines if it will float or sink in water. Some metals rust when submerged due to a chemical reaction with water and temperature can affect the metal's behavior. Studying this topic is significant for understanding metal properties and preventing damage to structures in water environments.

A metal rod and a metal ball more submerged in h2o, such that one end of the rod is adjacent to the ball. if the h2o will be heated from 30 k to 65 k, what is the acceleration of the ball? the initial length of the rod is 6 m.

Vball= 6 cm3
Vrod= 9 cm3
Crod= 13 cal/g.c degrees
Cball= 8 cal/g.c degrees
Ch2o= 1.0 cal/g.c degrees
Mball= 60 g
Mrod= 607 g
α= 0.005/c degrees


Topic is about Hydrostatic

I was absent during the assigning of this homework. I really need help! Thank you! :)

Related to A metal rod and a metal ball more submerged in H2O

1. What is the difference between a metal rod and a metal ball when submerged in H2O?

The main difference between a metal rod and a metal ball when submerged in H2O is their shape and surface area. A metal rod has a long and narrow shape, while a metal ball has a round shape. This means that a metal rod has a larger surface area in contact with the water compared to a metal ball, which results in a higher amount of water displacement and buoyancy force.

2. How does the density of the metal affect its buoyancy when submerged in H2O?

The density of a metal greatly affects its buoyancy when submerged in H2O. If the metal is less dense than water, it will float, as the buoyancy force will be greater than the weight of the object. If the metal is more dense than water, it will sink, as the weight of the object will be greater than the buoyancy force. The shape and volume of the metal also play a role in its buoyancy.

3. Why do some metals rust when submerged in H2O?

Some metals, such as iron and steel, rust when submerged in H2O because of a chemical reaction between the metal and the water. This is known as corrosion, and it occurs when oxygen and water react with the metal, causing it to break down and form a new compound. The presence of salt in the water can also speed up the rusting process.

4. How does the temperature of the water affect the metal when submerged in H2O?

The temperature of the water can affect the metal when submerged in H2O in several ways. When the water is colder, the metal will contract, and when the water is warmer, the metal will expand. This can cause stress on the metal, which may lead to cracks or other forms of damage. Additionally, warmer water can also accelerate the corrosion process.

5. What is the significance of studying the behavior of metals when submerged in H2O?

Studying the behavior of metals when submerged in H2O is important for various reasons. It helps us understand the properties of different metals, such as their density and buoyancy, and how they interact with water. This knowledge is essential for various industries, such as construction and marine engineering, where metals are often used in water environments. It also allows us to predict and prevent potential damage to metal structures caused by corrosion and other factors when submerged in water.
