Does channel stop sending or receiving data on coroutine scope cancellation?

I am new to kotlin coroutine, i am using Channel in my coroutine, I need to know whether the channel created in the particular scope will get cancelled once the scope get cancelled.

will the channels acts as a children in that scope?

Example

class TestingChannel {

    val channel = Channel<String>(Channel.BUFFERED)

    suspend fun start() {
        coroutineScope {
            awaitAll(
                async { startSendingData() },
                async { startReceiveData() }
            )
        }
    }

    suspend fun startSendingData() {
        channel.send("some_data")
    }

    suspend fun startReceiveData() {
        for (data in channel) {
            print(data)
        }
    }
}

class ViewModel : ViewModel() {

    init {
        viewModelScope.launch {
            TestingChannel().start()
        }
    }

    override fun onCleared() {
        super.onCleared()
        /**
         * on Clearing the viewmodel scope, will my channel in the that scope stop sending or receiving data
         */
    }
}

In the above code i don't use produce function since it is in experimental state. Can anyone help me with this?
