At higher pressure, the expansion takes more work. For example, in heating water from 10 C to 30 C, the density decreases from 999.7026 k g m 3 to 995.6502 k g m 3, so 1 k g of water expands by 2.066 ⋅ 10 − 6 m 3. can i give one week notice

"WebJul 11, 2024 · So when you consider the heat capacity as the volumetric heat capacity, the disparity between metals and plastic regarding how much thermal energy is available is much reduced. In my work in studying the thermal burn potential of different objects, I needed to consider the same volume of plastic and metal to compare apples to apples.
