Hot and Cold are relative to the system being measured. In effect they are subjective. Temperature is a quantitative measure of the relative change. When a system looses heat it is considered exothermic and vice-versa endothermic. But something that is considered cold to us can loose heat and become colder. It is therefore necessary to use a specific temperature when referring to the change.
"The weather is cold" is an observation because it is something you can feel. An inference is something you decide or think about an event after observing it. For example "The temperature must have dropped."

It depends on your country's legislation. In the UK, employment law states the temperature of businesses must be a minimum of 18 degrees Celsius within one hour of the start of the working day.+++A server room or similar in which no-one works except on maintenance tasks may be cold to keep the electronics cool, but the question does specify offices.
A measure of the average kinetic energy of a substance
Less than 40F.
Cold blooded organisms lack their own temperature regulators, and must maintain a constant temperature by external means. Colenteratas, such as coral and jellyfish are indeed coldblooded.
You must specify exactly what items you need for the meeting.
It must get below the freezing temperature of water before it snows in Australia. This is because the water in the clouds must be able to freeze.
Like most other substances, mercury takes up the temperature of its surroundings, so its average temperature must be room temperature, unless you put it into somewhere hot or somewhere cold.
No, the converse of a statement is not always true. In this case, if you wear a jacket, it does not necessarily mean that it must be cold; you may choose to wear a jacket for reasons other than cold temperature, such as fashion or personal preference.
They are cold blooded, which means that if the environment's temperature changes, their body temperatures change. So they must move to a colder area.
An amphibian has no internal temperature control and must rely on the weather to get hot or cold. So whatever the air temperature it is outside is the temperature of the amphibian. Or if it's in the water, it would be the temperature of the water it is in.
