to pass the olevel exam
To know how energy will move between two objects, you need to know their temperatures, masses, and thermal properties such as specific heat capacities. You also need to consider the distance between the objects and any medium through which heat can be transferred, such as air or water.
I would need to know the initial temperatures of the two objects, their specific heat capacities, surface areas in contact, and thermal conductivities. Additionally, the duration of contact and any external factors like temperature gradients or insulation would be important for a more accurate prediction of heat transfer.
Heat energy (gained/lost)= mass x specific heat capacity x temperature(rise/fall) Now with this expression we come to know that for a given mass and with a given amount of heat energy in joule, as sp. heat cap is more then rise / fall in temperature will be less and vice versa.
Reflect. Light-colored objects reflect heat and light, while dark-colored objects absorb heat and light.
I dont know really but i think is a low
i wanna know too .
All you need is their temperatures. If their temperatures are different, then heat will flow from the warmer one to the cooler one.
Normally you'd say something about the heat of formation. Exactly what that would be depends on the results you got, which we obviously don't know.
Yes it would. It has to do with the difference in heat transfer, the closer two objects are to being the same temperature, the slower they exchange heat. I know that there was a full explanation of this in a Scientific American article many years ago.
To calculate the amount of heat needed to raise the temperature of a substance, you can use the specific heat capacity formula, which is Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. The specific heat capacity varies depending on the substance, so you would need to know this value for each container.
To calculate heat energy when you know volume and temperature, you would need to use the formula Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Given volume, you would also need to know the density of the substance to calculate the mass.
I would definently think that the cause of heat illness would be, I don't know,...HEAT!maybe. I would definently think that the cause of heat illness would be, I don't know,...HEAT!maybe.
