名师精编优秀教案学业分层测评(十一)(建议用时：45 分钟)学业达标 1关于核力的下列说法正确的是()【导学号：64772106】A核力同万有引力没有区别，都是物体间的作用B核力就是电磁力C核力是短程力D核力与电荷有关【解析】核力是短程力，故C 对；核力与万有引力、电磁力不同，故A、B 不对；核力与电荷无关，故D 错【答案】C 2(多选)下列说法中正确的是()A质子与中子的质量不等，但质量数相等B两个质子之间，不管距离如何，核力总是大于库仑力C同一种元素的原子核有相同的质子数，但中子数可以不同D除万有引力外，两个中子之间不存在其他相互作用力【解析】质子和中子的质量不相等，但差别不大，质量数相等，故 A 对 核子之间的核力随距离变化而变化，并不总大于库仑力，故B 错同位素之间质子数相同，中子数不同，质量数也不同，故C 对核子之间除万有引力外，还可能存在核力、库仑力，但质子与中子之间、中子与中子之间没有库仑力，D 错误【答案】AC 3(多选)一个质子和一个中子结合成氘核时，产生 光子，由此可见()A氘核的质量等于质子和中子的质量之和B氘核的质量小于质子和中子的质量之和C核子结合成原子核时会释放核能名师精编优秀教案D原子核分解成核子时会释放核能【解析】由于结合时产生 光子，即产生能量，故反应中有质量亏损，但反应过程中质量数守恒，B 正确，A 错误质子和中子统称核子，该反应为核子结合成原子核的反应，故C 对，D 错【答案】BC 4(多选)关于原子核的结合能与平均结合能，下列说法中正确的是()【导学号：64772052】A原子核的结合能等于核子与核子之间结合成原子核时核力做的功B原子核的结合能等于核子从原子核中分离，外力克服核力做的功C平均结合能是核子与核子结合成原子核时平均每个核子放出的能量D不同原子核的平均结合能不同，重核的平均结合能比中等质量核的平均结合能大【解析】原子核中，核子与核子之间存在核力，要将核子从原子核中分离，需要外力克服核力做功 当自由核子结合成原子核时，核力将做功，释放能量对某种原子核，平均每个核子的结合能称为平均结合能不同原子核的平均结合能不同重核的平均结合能比中等质量核的平均结合能要小综上所述，正确选项为 A、B、C.【答案】ABC 5(多选)对公式 E mc2的正确理解是()A如果物体的能量减少了 E，它的质量也一定相应减少 mB如果物体的质量增加了 m，它的能量也一定相应增加 mc2C m 是某原子核在衰变过程中增加的质量D在把核子结合成原子核时，若放出的能量是 E，则这些核子的质量和与组成原子核的质量之差就是 m【解析】一定质量对应于一定的能量，物体的能量减少了 E，它的质量也一定相应减少 m，即发生质量亏损，如果物体的质量增加了 m，它的能量文档编码:CW7L9R1V1L8 HQ2X9V2N6H5 ZR9M9R8K1W4文档编码:CW7L9R1V1L8 HQ2X9V2N6H5
