A past participle ends in -ed or -en and it has two functions:

1) adjective

EX: This car is heated. (Verb: "is"; Adjective "heated")
EX: We had a heated argument. (Adjective "heated")

As an adjective, the past participle occurs after the verb BE (is, am, was, were, been) or it modifies a noun.

2) part of a verb

EX: The stove has heated the room. (Verb: "has"; Part of a verb: "heated")

As a part of a verb, the past participle occurs with the verb HAVE (have, has, had).

Past tense refers to a verb. (Please note that, past participles are not verbs.)

EX: The stove heated the room.

In the example above, the word 'heated' doesn't do the following things:

It doesn't occur with BE (is, am, was, were, been)
It doesn't occur with HAVE (have, has, have)
It doesn't modify a noun (argument)

"heated" functions all by itself. It's a verb, and the -ed ending tells us it's a past tense verb. :D

All the best, :D

Dear Mr. Casiopea ("Moderator"),

Thank you for all your replies. I've been reading them and you have been helping me.

Please alow me to ask the following question:

(1) The stove has heated the room (present perfect)

(2) The stove heated the room (simple past)

It is complicated for me to explain the difference between the two above, I mean, the meaning/the message of each one.

I appreciate your help,

"The stove has heated the room" means that, thanks to the stove, the room is now warm. The present perfect usually refers to the result of a past action.

"The stove heated the room" doesn't mean the room is still warm. I might say, for example: "The stove heated the room, but then some idiot opened the window and the room is cold again."

Heh, 1st result on google is this thread when searched "past participle and past tense" (without the quotes).

To anyone,

Like what Casiopea said, you only use past participles for:
BE (is, am, was, were, been)
HAVE (have, has, had); part of a verb

Is this correct? Because it sounds weird to me...
"The bird is flown." (Verb: is; Adjective: flown)
"The bird has flown." (Verb: has; Part of a verb: flown)

This sounds correct to me:
"The smoke is risen."
"The stove is heated."
"The smoke has risen."
"The risen smoke." (Adjective: risen)
"The smoke rose." (Past tense verb: rose)

Thanks all....
