What else can I help you with?
How would you describe the two ways cumulative risks occur?
Occur by the increase of effect of one risk or of each added risk
What does the intersection of two lines occur at?
A point.
What are congruent halves?
They occur when you divide something on a line of symmetry.
What is the definition of critical angle?
The definition of critical angle is the angle of incidence that refraction can still occur.
What is the difference in size of carrot in diamond?
Carat is a weight indicator of diamonds. Carrots are vegetables, which don't occur in diamonds.
What Type of energy transformation occur in an iron?
When an iron is heated, the electrical energy is transformed into thermal energy. The atoms in the iron vibrate faster and collide with one another, leading to an increase in temperature.
Does evaporation only happen when water is heated to high temperature?
Evaporation occur at any temperature.
What are thermal expansion and contractions?
Thermal expansion is the tendency of a material to increase in size when heated, while thermal contraction is the tendency of a material to shrink when cooled. These phenomena occur as the particles within the material gain or lose kinetic energy, causing them to move and vibrate more or less vigorously, respectively. Thermal expansion and contraction can lead to dimensional changes in objects when exposed to temperature fluctuations.
If the temperature increases in the water of lakes and streams then what type of pollution may occur?
thermal pollution
The flow of thermal energy?
Thermal energy flows from an object with a higher temperature to one with a lower temperature until thermal equilibrium is reached. This flow can occur through conduction, convection, or radiation, depending on the medium through which the energy is transferring. The rate of heat transfer is dependent on factors such as the temperature difference, the thermal conductivity of the material, and the surface area involved.
What is the process by which thermal energy moves from a region of higher temperature to a region of lower temperature?
The process by which thermal energy moves from a region of higher temperature to a region of lower temperature is called heat transfer. This can occur through three main methods: conduction, convection, and radiation.
Are nitrogen and hydrogen heated in Haber process?
Yes, they are heated in a ratio of 1:3. The temperature should be 400 degrees celcius. The pressure should be 2-3 atm.
What physical changes occur to thermal conductivity?
because atoms expands when temperature increases in result physical changes.
What problems can occur with thermal cutting and how they can be avoided?
Some problems with thermal cutting can include distortion of the material, excessive heat affected zone, and dross formation. These issues can be avoided by using the appropriate cutting parameters, ensuring good material clamping to prevent movement, and using high-quality consumables to maintain a clean cutting process. Regular maintenance of the cutting equipment and proper ventilation can also help in preventing problems.
Thermal energy transferred between objects which have different temperature?
A transfer of heat (H) energy does not occur without a temperature differential. If the two objects had different amounts of H then a transfer would indeed occur. In this case heat would flow from a higher to lower temperature object.
What temperature does thermal decomposition occur at for magnesium carbonate?
Thermal decomposition of magnesium carbonate occurs at around 350-400°C. At this temperature, magnesium carbonate breaks down into magnesium oxide and carbon dioxide.
Where does thermal expansion and contraction occur?
Thermal expansion and contraction occur in materials when they are exposed to changes in temperature. This can happen in solids, liquids, and gases, leading to changes in volume, length, or density of the material. It is a common phenomenon experienced in everyday objects and structures.
