the largest temperature decline during a 1 day (24 hours) time period was 56 degrees Celsius in Browning, Montana. Express this as degrees Fahrenheit per minute

0.0922 Fahrenheit per minute

Explanation: Temperature change in degree Fahrenheit from Celsius is given by multiplying the change in temperature in celsius by 1.8 and adding 32 to it. Now the temperature you added is in Fahrenheit. But the temperature change is for a day. To convert change in temperature per day to per minute divide the obtained answer in Fahrenheit by 24*60.

Thus,

change in temperature in Fahrenheit: (56*1.8)+32= 132.8 degree Fahrenheit

change in temperature per minute: (132.8)/(24*60)= 0.0922 degree Fahrenheit per minute

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
