选一个并说明一下原因,
The combination of temperature and pressure______the densities become equal is called the critical point.
A.in which B.that C.at which D.on that

选一个并说明一下原因,The combination of temperature and pressure______the densities become equal is called the critical point.A.in which B.that C.at which D.on that
C
温度和压力组合在该密度成为平等的这一点被称为临界点.
at which作为定语从句的引导词,等于where.
The combination of temperature and pressure is called the critical point.
The densities becomes at the critical point.

C ， temperature前面用AT

C
不知道这是哪个门类的，热力学吗？就是说一种物质在温度A的密度和在压力B的密度是一样的，然后A和B的组合就是他的critical point。
所谓at which是the density at temperature and the density at pressure B

并说明一下原因 I hear the sound of _____(ruch)water in the kitchen .并说明一下原因, 选一个并说明一下原因,The combination of temperature and pressure______the densities become equal is called the critical point.A.in which B.that C.at which D.on that it is the time ( ) i go to school .a:when b:that请说明一下原因,并传授一下心得. It is spring,Class 4 of our school ____ near the school.A is planting B.are planting 选什么并请说明一下原因, I can't decide（） the best time is to go thereA what B when C whether D which 说一下原因,并说明不选B和C的原因 26并说明原因～并说明原因... 并说明原因. 解答并说明原因并说明原因. 并说明下原因, 并说明原因并请说明原因解答并说明原因. 并说明原因, 并说明原因谢谢! 并说明原因喔
