已知冰的密度是917kg/m^3,水的密度是1000kg/m^3。水的熔化潜热约为333J/g。已知冰的熔点为0℃,熔点为1.01325×105Pa。根据这一信息近似,求...
已知冰的密度是917kg /m^3,水的密度是1000kg /m^3。水的熔化潜热约为333 J/g。已知冰的熔点为0℃,熔点为1.01325×105Pa。根据这一信息近似,求出冰块在-2.7℃熔化的压力。假设相位边界是线性的。
Given that the density of ice is 917 kg/m^3 and the density of water is 1000 kg/m^3. The latent heat of fusion for water is roughly 333 J/g. It is known that ice melts at 0oC at 1.01325×105Pa. Approximating from this information, find the pressure for an ice cube to melt at –2.7 oC. Assuming the phase boundary is linear. 展开
