During brisk walking, the pulse can increase to around 100-130 beats per minute. This elevated heart rate is a result of the increased demand for oxygen and energy by the muscles during the activity. It is a normal and beneficial response to exercise, as it helps to improve cardiovascular fitness and endurance. However, it is important to monitor your heart rate during exercise and consult with a healthcare professional if you have any concerns about your heart health. **

Yes, dry rust can continue to rust. Rust is a chemical reaction between iron, oxygen, and water, and even in the absence of liquid water, rusting can still occur through a process called dry corrosion. This occurs when moisture in the air or other environmental factors provide enough water vapor to sustain the rusting process. Therefore, even if the rust appears dry, it can still continue to corrode over time. **

The number of calories burned in one hour of brisk walking can vary depending on factors such as a person's weight, pace, and intensity of the walk. On average, a person weighing around 155 pounds can burn approximately 280-350 calories per hour of brisk walking. However, individuals who weigh more may burn more calories, while those who weigh less may burn fewer calories. It is important to note that these are rough estimates and actual calorie burn can vary. **

Yes, as an apprentice, you may be required to write reports by hand. This can be a valuable skill to develop as it can improve your handwriting, attention to detail, and overall communication abilities. However, many workplaces now use digital tools for report writing, so it is important to be proficient in both handwritten and digital report writing as an apprentice. **

Rust is a reddish-brown coating that forms on iron or steel when it is exposed to oxygen and moisture. It is a chemical reaction known as oxidation, where the iron in the metal combines with oxygen in the air to form iron oxide. Rust weakens the metal and can eventually cause it to deteriorate and break down if not treated or prevented. It is commonly seen on metal objects like cars, tools, and outdoor furniture. **

Rust is promoted by the presence of moisture and oxygen, which create the ideal conditions for the oxidation of iron and steel. Additionally, exposure to salt, particularly in coastal areas or on roads where salt is used for de-icing, can accelerate the rusting process. Other factors that can promote rust include high humidity, acidic environments, and the presence of certain chemicals or pollutants. Regular maintenance and protective coatings can help prevent rust from forming on metal surfaces. **

No, plastic cannot rust because rusting is a chemical reaction that occurs in metals when they are exposed to oxygen and water. Plastic is a synthetic material made from polymers, which do not contain metal elements that can undergo rusting. However, plastic can degrade over time due to exposure to sunlight, heat, and certain chemicals, leading to cracking, discoloration, and weakening of the material. **
