student decides to dissolve calcium chloride (salt) in water. When calcium chloride is dissolved in water, it creates an exothermic reaction. The student
places the calcium chloride and water in a plastic bag and then places the ice cube on top of the bag.
Which of these would increase the heat generated and reduce the time it takes the ice cube to melt?
Increasing the size of the ice cube to be melted.
Increasing the amount of calcium chloride placed in the bag.
Increasing the size of the plastic bag.
Dropping the ice cube in the bag with the calcium chloride and water and then shaking the bag.
Putting more water and less calcium chloride in the bag.
Doubling the size of the plastic bag and doubling the amount of water and calcium chloride used,

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

sup bro, im dumb, but this is what i found xd

"the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface"
