1. Liquid helium was used for science at very low temperatures.

True

False

Not Given

Liquid helium is commonly used in scientific research and experiments that require extremely low temperatures. It has unique properties that make it ideal for cooling and studying various materials and phenomena. Its low boiling point of -268.93°C (-452.07°F) allows it to reach temperatures close to absolute zero, making it a valuable tool in fields such as physics, chemistry, and materials science. Therefore, the statement "Liquid helium was used for science at very low temperatures" is true.

6. Venus' thick clouds are made of _____ .

Venus' thick clouds are composed of sulphuric acid. This is due to the high temperatures and pressure in Venus' atmosphere, which cause sulfur dioxide and water vapor to react and form sulphuric acid. The clouds of sulphuric acid on Venus create a dense and opaque layer that obscures the planet's surface from view.

7. Superconductors that work at higher temperatures are more expensive.

True

False

Not Given

The given statement is "Superconductors that work at higher temperatures are more expensive." The correct answer is False. This means that superconductors that work at higher temperatures are not more expensive. This suggests that the cost of superconductors is not directly proportional to the temperature at which they operate.

Explanation

The given statement is "Superconductors that work at higher temperatures are more expensive." The correct answer is False. This means that superconductors that work at higher temperatures are not more expensive. This suggests that the cost of superconductors is not directly proportional to the temperature at which they operate.

9. It is highly likely that there was _____ on Venus in the past.

There is a high probability that there was water on Venus in the past. This assumption is based on various scientific studies and observations that suggest the presence of liquid water on the planet's surface billions of years ago. These studies include the detection of certain geological features on Venus that are typically formed by the action of water, as well as the presence of deuterium, a heavy isotope of hydrogen that is often associated with water. Additionally, the planet's proximity to the Sun and its relatively similar size to Earth further support the possibility of water being present on Venus in the past.

10. Venus is a much _____ planet than it used to be.

The correct answer is "hotter" because Venus has experienced a significant increase in its surface temperature over time. This can be attributed to the greenhouse effect caused by the thick atmosphere composed mainly of carbon dioxide. The greenhouse gases trap heat from the Sun, leading to a rise in temperature on the planet's surface. As a result, Venus has become hotter compared to its previous state.

11. The spacecraft Magellan used _____ to create pictures of the surface of Venus.

The spacecraft Magellan used radar to create pictures of the surface of Venus. Radar is a technology that uses radio waves to detect and map objects, and it was utilized by Magellan to penetrate Venus' thick atmosphere and gather data about its surface features. By bouncing radio waves off the planet's surface and measuring the time it took for the waves to return, Magellan was able to create detailed images of Venus' topography.
