Central nervous system- central nervous system consists of the brains and spinal cord. brain is the main controlling part of nervous system and it is safely located in the cranial cavity. In the space between the delicate central nervous system and its bony covering are the protective layers called the meninges.cavities present in various parts of the brain are called as ventricles. the long tubular cavity of spinal cord is called as central canal. spinal cord is held within vertebral column. it is slightly thick but gradually tapers towards the end. there is thread like fibrous structure at its end called as filum terminal. peripheral nervous system- the peripheral nervous system consists of the nerves originating from the central nervous system. these nerves connect the central nervous system with all parts of the body. they are of two types-A) cranial nervesnerves originating from the brain are called cranial nerves.bthey are associated with various parts in the head , thorax and abdomen. these are 12 pairs of cranial nerves.B) spinal nervesnerves originating from the spinal cord are called spinal nerves. these are associated with the arms, legs, stomach, etc . it is not under the control of our will. |

3, Whul İs meuril by specific heatcapacity? How will you proveexperimentally that differentsub、IUI1Ces h(JV (' different 、pecificheat capacities? |
Answer» Specific Heat : The amount of heat needed to raise the temperature of 1 kg substance by 1° C. Basics of Experiment; Understanding:1) When hot and cold substances are mixed in a insulated container such as a calirimeter , heat will flow from hot substance to cold substance .2) Assuming heat absorbed by the container and heat lost to the environment are both negligible .Then, we will use Heat lost by the hot substance = Heat gained by the cold substance. In this experiment, we will find that temperature change will be different for different substances. Hence, different substances has different specific heat capacities. |
