The Mechanical Section has introduced the \"Question of the Day\" feature, which not only helps to foster an active atmosphere for technical discussions and guide the direction of such exchanges but also provides users with financial rewards, enabling them to experience various cool features. 【Daily Question】Which of the following statements about viscosity is incorrect? ( ) A. Both stationary and flowing fluids possess viscosity. B. Viscosity is a physical quantity that measures the degree of viscosity of a fluid. C. The viscosity of a fluid decreases as the temperature rises. D. Changes in pressure have little effect on the viscosity of liquids, and this effect can be ignored; similarly, changes in pressure have little impact on the viscosity of gases as well. Answer: C. Requirements and hints for answering the question: Please reply with the answer you think is correct. If you provide a detailed explanation or analysis of the question and answer, you will receive an additional reward. Extra rewards will be given if your answer is correct and your explanation is thorough and accurate. Feel free to answer the questions. Please note: We will close this thread after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation. Please do not answer the question repeatedly. As a reward for your effort, if you post a topic in this section within two days that provides a detailed explanation of the knowledge points related to this question, please reply or leave a comment in this post to let us know; we will then have a moderator award you + Charm. It is not allowed to simply copy and paste; original content is preferred, with at least some organization by the user along with personal insights and opinions.

Which of the following statements about viscosity is incorrect? C. The viscosity of a fluid decreases as the temperature rises
C feels like this is the right thing to do.
Without a doubt, the first three are correct, D is wrong, and the second half is incorrect
The incorrect statement regarding viscosity is (C). A. Both stationary and flowing fluids possess viscosity. B. Viscosity is a physical quantity that measures the degree of viscosity of a fluid. C. The viscosity of a fluid decreases as the temperature rises. D. Changes in pressure have little effect on the viscosity of liquids, and this effect can be ignored; similarly, changes in pressure have a negligible impact on the viscosity of gases. The viscosity of liquids decreases as the temperature increases, while the viscosity of gases increases as the temperature rises
The incorrect statement regarding viscosity and stickiness is (C)
