Answer: Thus the pressure of the air in a car tire in psi is 25.4
Explanation:
Pressure is defined as the force exerted per unit area.
Thus units of pressure can be atm or psi or Pa.
Given :
Convert 1.73 atm to psi units
1 atm = 14.7 psi
Thus 1.73 atm =
Thus the pressure of the air in a car tire in psi is 25.4
Answer:
Atomic Number: 1
Atomic Mass: 1
Explanation:
Atomic number = # of protons
Atomic mass = # of protons + # of neutrons
The investigation was carried out to explore the effect of amylase on the starch that is present in a substance. The IKI solution reacts with starch to give a dark blue color.
We wait 10 minutes before adding the IKI solution to give the amylase sufficient time to act on the starch present, so that a false negative for the presence of starch is not obtained.
Answer:
igneous rocks are made from molten,and therefore rarely have fossils in them.Metamorphic rocks are squished,put under pressure,and get heated to the extreme,so it's very rare for fossils to survive in these conditions.
