Hi Raj,
Just Call Database.executeBatch(new BatchOppUpdate(contactsToUpdate)); in Trigger on update event then define a batch class as follows:-

global class BatchOppUpdate implements Database.Batchable<sObject>{

List<Account> parentAccount = new List<Account>(); 
List<Opportunity> Opplist1 = new List<Opportunity>();

 global BatchOppUpdate(List<Account> AccountUpdate) {
      parentAccount = AccountUpdate; 

global Database.QueryLocator start(Database.BatchableContext BC) { 
    return DataBase.getQueryLocator([SELECT Id, AccountID FROM Opportunity WHERE AccountID IN :parentAccount ]); 

global void execute(Database.BatchableContext BC , List <Opportunity> Opplist) { 
    for (Account acct : mapAccount){ 
        for (Opportunity opp : contactList){ 
             if (opp.AccountID == acct.Id){ 
                 Opplist1.add(new Opportunity( Id = opp.Id, ); 
update Opplist1; 

global void finish(Database.BatchableContext BC){ 


If It really helps you please give it as best answere :)
