B. Test a hypothesis by gathering data
Seriously though, what type of guy thinks "oh hey there's a transperent liquid in the science lab? yeah it's water."
Answer:
A: catalyst
Explanation:
In Chemistry, the rate of reaction of chemical elements (reactants) can be sped to produce a chemical compound or elements (products), through the addition of a catalyst that is unaffected by the reaction.
This ultimately implies that, to speed up a chemical reaction, add a catalyst that is unaffected by a reaction.
For example, an enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Generally, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
Answer Water, wind, and ice can also move pieces of rock or land to new places. The wearing away of a surface of rock or soil is called weathering. ... Weathering and erosion can cause changes to the shape, size, and texture of different landforms (such as mountains, riverbeds, beaches, etc).:
Explanation:
Earth takes in thermal energy from the Sun in a process called thermal radiation.
Sunlight strikes Earth's surface at different angles. This angle is called the angle of insolation.
<h3>What is thermal energy?</h3>
Thermal energy refers to the energy contained within a system that is responsible for its temperature.
Earth takes in thermal energy from the Sun in a process called thermal radiation.
Sunlight strikes Earth's surface at different angles. This angle is called the angle of insolation.
