What does it mean that forces can be added or subtracted?
Forces can be added or subtracted when they act in the same or opposite directions, respectively, on an object. When forces are added, their magnitudes combine to produce a net force on the object. When forces are subtracted, their magnitudes are compared to determine the resultant force acting on the object.
What happens to ice when heat energy is added?
When heat energy is added to ice, the ice melts and turns into water. This process is called melting. As more heat energy is added, the water will continue to heat up until it reaches its boiling point, at which point it will turn into steam.
The change in an objects volume that occurs when heat is added is called?
thermal expansion
A difference in the results in different ending temperatures when the same amount of thermal energy is added to two different substances is called what?
That difference is called specific heat capacity. Specific heat capacity is a measure of how much heat energy is required to raise the temperature of a substance by a certain amount, so substances with different specific heat capacities will experience different temperature changes when the same amount of thermal energy is added.
What is it called expenses such as heat light and salaries?
Operating expenses refer to costs incurred by a business in its day-to-day operations, such as utilities (heat, light), salaries, rent, and office supplies. These expenses are necessary for running the business and are subtracted from revenue to calculate a company's operating profit.
