The temperature of 2.0 g of helium is increased at constant volume by δt. what mass of oxygen can have its temperature increased by the same amount at constant volume using the same amount of heat?

m = 9.6 g

Explanation:

Thermal energy given to helium gas at constant volume is given as

so here we have

so we have

now we know that

for oxygen gas we have

for same amount of heat we have

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )
