WebFor water and most solids/liquids, yes but very slightly. When you heat the water it expands, which does work against the surrounding pressure. 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 …
