Students were investigating thermal energy. They put a metal spoon in the freezer. They put hot water in a beaker and measured the water temperature. They removed the spoon from the freezer and put it in the beaker. After 10 minutes, the students measured the water temperature again and touched the spoon. The data are shown in the table. Student Investigation Start of Investigation After 10 Minutes Water temperature (°C) Feel of spoon Water temperature (°C) Feel of spoon 43 Cold 41 Warm Which best describes how the thermal energy in the water and in the spoon changed during the investigation?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
