Answer:
1. Independent variable : pendulum's height
2. Dependent variable : Pendulum speed
Explanation:
In an experiment scientist uses such things to search for any cause and its effect. experimenters design the model in such a way that change in one of the item causes a change in another.
These are called variables which are independent variable and dependent variable. Independent variables can be changed by the experimenter while dependent variables are not controllable by the experimenter.
In the context, the hypothesis is when the pendulum's height is reduced, the clock will speed up.
1. Independent variable : height of the pendulum
2. Dependent variable : Pendulum speed

Answer:
The temperature of the gas is 876.69 Kelvin
Explanation:
Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:
P*V = n*R*T
where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas.
In this case:
- P= 470 mmHg
- V= 570 mL= 0.570 L
- n= 0.216 g= 0.0049 moles (being the molar mass of carbon dioxide is 44 g/mole)
- R= 62.36367

Replacing:
470 mmHg*0.570 L= 0.0049 moles* 62.36367
*T
Solving:

T= 876.69 K
<em><u>The temperature of the gas is 876.69 Kelvin</u></em>
