The following options have changed viscosity of honey
A. The temperature of honey by heating it in water
B. The consistency of honey by adding sugar to it
D. The temperature of honey by laying it out in the sun
Explanation:
- Let us define viscosity, it is defined as a liquid is being resistant to move freely caused by the internal friction in the liquid. There are several factors which change viscosity by affecting the internal friction.
- Those factors could be an external force, temperature, adding substances like sugar can change the consistency, etc
- For liquids, the temperature has an inverse relation with the viscosity of the liquid. Liquids will have greater viscosity when there is a low temperature. Here, when you heat the honey the viscosity reduces as temperature increases.
Answer:
Explanation:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing
