What else can I help you with?
How does selection control structures increase the usefulness of a computer program?
A computer is a computer more can happen to it
What is the effect of heat and cold?
Heat can cause expansion of materials, increase in molecular movement, and chemical reactions to occur more readily. Cold can cause contraction of materials, decrease in molecular movement, and slow down chemical reactions. Both heat and cold can impact the physical, chemical, and biological properties of substances.
Do enzymes decrease the rate of chemical reactions?
No, they Increase the speed of chemical reactions
What does an increase in temperature result to?
An increase in temperature can lead to the expansion of materials, a change in state (for example, from solid to liquid), an increase in the speed of chemical reactions, and can also cause biological processes to speed up or slow down.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
Which condition leads to an increase in supply?
an increase in the cost of raw materials
Is it possible for anyof the earth's materials scenes to be affected by both mechanical and chemical weathering?
Yes, it is possible for Earth's materials to be affected by both mechanical and chemical weathering concurrently. Mechanical weathering physically breaks down rocks into smaller pieces, which can increase their surface area and make them more susceptible to chemical weathering processes, such as hydration, oxidation, or acid rain. Together, these processes can alter the composition and structure of the materials over time.
What is One way to increase the rates of chemical reactions is to increase what?
Catalyst
What material can absorb light?
Materials that can absorb light well include carbon-based materials like charcoal, pigments in paints, and dark colored fabrics. These materials have the ability to absorb light energy due to their chemical composition and structure, resulting in a decrease in reflected light and an increase in absorbed light.
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
What is increase in chemical permeability in the epidermis due to?
increase in the spacing between cells
How you describe the changes that happened to the materials when heated?
When materials are heated, they can undergo physical or chemical changes. Physical changes include state changes like melting or boiling, while chemical changes involve the molecules rearranging to form new substances. Heating can also increase the kinetic energy of molecules, causing them to move faster and potentially break bonds.
