Ture of False Questions in Science(Please help me) (20)

Question

Decide whether the following statements are ture or not, and then circle"Ture" or "False".

1.The suction hook we frequently use in the bathrooms can stick to the wall because of the presence of the atmospheric pressure. (Ture or False)

2.If the number of gas particles in a closed can increases,the gas pressure is also increased. (Ture or False)

3.We are hit constanthy by air particles,so pressure is exerted on us. (Ture or False)

Answer 1

1. T Gas between the suction hook and wall is driven out and the atmosphere press the hook to the wall.
2. T When no. of gas particles increase. the number of particle collided with the can per second also increase, it increase the pressure.
3. T the atmospheric pressure put on our body is just for this reason.

Answer 2

1.The suction hook we frequently use in the bathrooms can stick to the wall because of the presence of the atmospheric pressure. (Ture or False)

Is ture,because 1. Celsius.2. Centigrade. 3. In heat transfer, conduction of a material to the passage of heat; the reciprocal of resistance (C=1/R). 4. In seismic design, the numerical coefficient used which represents building acceleration. 5. Capacitance.

2.If the number of gas particles in a closed can increases,the gas pressure is also increased. (Ture or False)

Is ture also, because The exchange of gases is a simple process in small, aquatic organisms such as paramecium. Dissolved oxygen from the water diffuses into the cells, carbon dioxide diffuses out, a special respiratory system is not needed. The size of organisms is small, in case of protozoan, which is unicellular, the body is a cell, which is not far from the external medium. The rate of diffusion is fast enough to provide enough oxygen and to remove the carbon dioxide accumulated in the cell.

3.We are hit constanthy by air particles,so pressure is exerted on us. (Ture or False)

Is also ture,becauseTo delete "but as both petrol and diesel vehicles attribute to air pollution and before it can be confirmed which one of the two types of vehicle is more environment-friendly," and substitute with "and"; to insert "public response to" after "the Administration to review"; to delete the word "mandatory"; to delete "replace" and substitute with "amend"; to delete "with incentive measures to attract owners of diesel vehicles to change to petrol vehicles on a voluntarily basis, as well as to expeditiously" and subsitute with "to make it as widely acceptable as possible to the public and owners of diesel vehicles, including reconsideration of the proposed principle of revenue neutrality by agreeing to plough back any possible revenue so acquired into health care development and, to continue to"; and to delete "which are more effective and generally accepted by the public,"."
