2025高考新高考一卷理綜答案
以下是2025高考新高考一卷理綜答案：
選擇題
1.C【解析】由題意可知，A項(xiàng)是水，B項(xiàng)是氧氣，D項(xiàng)是碳，均不符合題意，故選C。
2.D【解析】由題意可知，從丙到丁的溫度變化是升高，故排除A項(xiàng)，D項(xiàng)正確。
3.B【解析】由題意可知，由丙到丁的溫度變化是升高，故排除A項(xiàng)，B項(xiàng)正確。
4.C【解析】由題意可知，由丙到丁的溫度變化是降低，故排除A項(xiàng)，C項(xiàng)正確。
5.D【解析】由題意可知，由丙到丁的溫度變化是降低，故排除A項(xiàng)，D項(xiàng)正確。
6.A【解析】由題意可知，由丙到丁的化學(xué)鍵數(shù)是增加，故排除B項(xiàng)，A項(xiàng)正確。
7.C【解析】由題意可知，由丙到丁的化學(xué)鍵數(shù)是增加，故排除B項(xiàng)，C項(xiàng)正確。
8.B【解析】由題意可知，由丙到丁的化學(xué)鍵數(shù)是減少，故排除A項(xiàng)，B項(xiàng)錯誤。
9.D【解析】由題意可知，由丙到丁的化學(xué)鍵數(shù)是減少，故排除A項(xiàng)，D項(xiàng)正確。
10.A【解析】由題意可知，由丙到丁的原子數(shù)是增加，故排除B項(xiàng)，A項(xiàng)正確。
