What is the relationship between air temperature and humidity 10 pts a. cold air is usually more humid than warm air. b. warm air and cold air have the same humidity level. c. warm air is usually more humid than cold air. d. there is no connection between temperature and humidity

C.Warm air is usually more humid than cold air.

as the temperature increase, vapor pressure increase. this in turn decreases the humidity, hence the air can hold more water at high temperature.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
