Q

Athrú Fisiceach

A

Nuair a athraítear substaint go fisiciúil (athraítear leagan amach cáithníní an ábhair) agus an fuinneamh atá iontu, ach ní athraítear na cáithníní iad féin.

Fuinneamh Gníomhachtúcháin

A

Q

Athrú Ceimiceach

A

Is éard is imoibriú ceimiceach ann ná athrú a tharlaíonn nuair a imoibríonn dhá shubstaint, nó níos mó, le chéile chun substaintí nua a chumadh.

Q

ráta imoibrithe

A

Is éard is an ráta imoibrithe ann ná cé chomh tapaigh nó cé chomh mall is a tarlaíonn an t-imoibriú ceimiceach.

Q

An Teoiric Inbhuailte

A

Nuair a chuirtear dhá imoibreáin nó níos mó le chéile i dtriailfheadán nó eascra, gluaiseann cáithníní na substaintí sin timpeall.

Q

Dlí Imchoimeád na Maise

A

Ní féidir mais shubstainte a chruthú nó a scroisadh, mar sin, le linn athrú fisiceach no athrú ceimiceach ní bhíonn aon athrú sa mhais.

Q

Nádúr na himoibreáin (nature of reactants)

A

Braitheann an ráta imoibrithe ar an gcineál ceimiceán a imoibríonn le chéile.
