뜨거운 물이 찬물보다 무겁다?
C, 화씨 39.2도)와 뜨거운 물을 비교하면,찬물이 뜨거운 물보다 무겁다. 학생들은 찬물을 뜨거운 물 위에 놓았을 때 가라앉고 뜨거운 물이 찬물 표면에 뜨는 것을 관찰해야 합니다.

(지식 브런치)
뜨거운 물이 더 무겁다?
분자 사이에 더 많은 공간이 있기 때문에 뜨거운 물의 부피는 더 적은 분자를 포함하고같은 부피의 냉수보다 약간 가벼운 무게. 따라서 뜨거운 물은 찬물보다 밀도가 작습니다.

더위와 추위 중 어느 쪽이 더 무겁습니까?
차가운 공기와 뜨거운 공기 중 어느 것이 더 무겁습니까?차가운 공기는 항상 같은 부피의 따뜻한 공기보다 무겁습니다.. "공기"는 실제로 여러 기체의 혼합물입니다. 부피 기준으로 건조한 공기에는 78.09%의 질소, 20.95%의 산소, 0.93%의 아르곤, 0.039%의 이산화탄소 및 소량의 기타 가스가 포함되어 있습니다.

(공돌이 용달)
추위가 더운 것보다 무거운 이유는 무엇입니까?
물질을 냉각하면 분자의 속도가 느려지고 서로 조금 더 가까워져 더 작은 부피를 차지하게 되어 밀도가 증가합니다.. 따뜻한 물은 밀도가 낮고 상온에서 물 위에 뜹니다. 찬물은 밀도가 더 높아 상온의 물에 가라앉습니다.

(건빵박사사이언스캠프)
온도가 물의 무게에 영향을 줍니까?
물의 밀도는 밀리리터당 약 1그램이지만,온도에 따라 변한다또는 용해된 물질이 있는 경우. 얼음은 액체 상태의 물보다 밀도가 낮기 때문에 각얼음이 유리잔에 떠 있는 것입니다.
(Video) 찬 물과 뜨거운 물은 섞이지 않는다고?
(찌니의 병맛실험)
물을 데우면 밀도가 낮아지나요?
물이 가열되면 물 분자가 더 빨리 움직이고 더 많이 퍼집니다. 이것은 뜨거운 물을 상온의 물보다 덜 조밀하게 만듭니다..

(List 25)
찬물과 뜨거운 물을 섞는 것이 맞습니까?
뜨거운 물과 차가운 물을 섞으면 중간 온도에 도달합니다.왜냐하면: (A) 열은 고온체에서 저온체로 흐른다. (B) 찬물을 뜨거운 물에 부으면 두 유체가 균일하게 혼합되어 열 전달 과정이 가속화됩니다.

가열하면 물건이 무거워집니까?
심.같은 온도에 있을 때 정확히 같은 무게를 가진 절대적으로 동일한 물체가 있는 경우 물체를 가열하면 무게가 더 많이 나갑니다.. 이것은 중력이 일반 상대성 이론에서 응력 에너지 텐서에 의존하기 때문입니다.

뜨거운 물은 찬물보다 얼마나 무거울까?
온수는 열팽창으로 인해 냉수보다 밀도가 낮습니다. 하지만:뜨거운 물 1파운드의 무게는 찬물 1파운드와 같습니다.— 무겁지도 가볍지도 않습니다. 그러나 더 많은 양을 차지합니다.
